Liver homogenate-supernatants from most Japanese exhibit an atypical pH optimum for ethanol oxidation at pH 8.8 instead of 10.5, the typical pH-activity optimum. It has been proposed that atypical livers contain alcohol dehydrogenase isozymes with 2 subunits while typical livers contain isozymes with 1 subunits, both produced by the ADH
2 gene. Because it is difficult to differentiate the atypical ADH2 2-2 phenotype from the ADH2 2-1 phenotype by starch gel electrophoresis, an agarose isoelectric focusing procedure was developed that clearly separated the atypical Japanese livers into two groups, A1 and A2. The isozymes in A1 and A2 livers were purified. Type A1 livers contained a single isozyme with an atypical pH-rate profile; it was designated 22. Three isozymes were isolated from A2 livers, two of which corresponded to 11 and 22. A third, absent from the typical and the atypical A1 livers, had an intermediate mobility; it was designated 21. Type A1 livers are, therefore, the homozygous ADH2 2-2 phenotype, and type A2 livers, the heterozygous ADH2 2-1 phenotype. The ADH2 2-2 phenotype was found in 53% of 194 Japanese livers, and the ADH2 2-1 phenotype, in 31%. Accordingly, the frequency of ADH

A novel syrup containing neofructo-oligosaccharides was produced from sucrose (Brix 70) by whole cells of Penicillium citrinum. The efficiency of fructo-oligosaccharides production was more than 55% and those of the main carbohydrate components, 1-kestose (Fruf 21Fruf 21 Glc), nystose (Fruf 21Fruf 21 Fruf 21 Glc) and neokestose (Fruf 26 Glc12 Fruf), were 22, 14 and 11%, respectively. 相似文献

Summary Soluble lead salts and a number of lead-containing minerals catalyze the formation of oligonucleotides from nucleoside 5-phosphorimidazolides. The effectiveness of lead compounds correlates strongly with their solubility. Under optimal conditions we were able to obtain 18% of pentamer and higher oligomers from ImpA. Reactions involving ImpU gave smaller yields.Abbreviations A

A broad-host-range plasmid (pEA2-21) containing a Bradyrhizobium sp (F-4) nod DABC-lacZ translation fusion was constructed and used to monitor nod gene expression in response to pigeonpea root exudate. Two nod-inducing compounds were isolated and identified. Spectral analysis using ultraviolet absorption, infrared spectra, proton nuclear magnetic resonance, and mass spectrometry showed that the two inducers were 5,4-dihydroxy-6-(3-methyl-2-butenyl)-2, 2-dimethyl pyrano-[5, 6:7, 8]-flavanone (cajaflavanone) and 2,4,5-trihydroxy-5-isopentenyl-6, 7-dimethylchromene iso-flavanone (cajanone). When pEA2-21 was introduced into Rhizobium trifolii and R. meliloti cajanone and cajaflavanone did not induce nod gene indicating that specificity of induction appears to be influenced by the host-strain genome. 相似文献

Plant rgeneration occurred on leaf-and stem-derived callus of Cuphea ericoides Cham. & Schlechtd obtained in Murashige and Skoog medium supplemented with auxins [indole-3-acetic acid (IAA), -naphthaleneacetic acid (NAA) or 2,4-dichlorophenoxyacetic acid (2,4-d)] plus cytokinins [6-benzyladenine (BA) or kinetin]. These calluses were subcultured and showed vigorous growth. When subcultured on medium containing 2.22 or 4.44 M BA, the calluses showed profuse regeneration of shoots whereas those subcultured on medium supplemented with 2.69 M NAA or 0.226 M 2,4-d produced numerous roots. Isolated shoots rooted on Murashige and Skoog medium lacking growth regulators or containing 0.54 M NAA or 0.49 M indole-3-butyric acid (IBA).

ATP synthesis associated with the conversion of hexachlorocyclohexane related compounds 总被引:3,自引:0,他引:3
Clostridium rectum strain S-17 converts -1,2,3,4,5,6-hexachlorocyclohexane (HCH) related compounds to chlorobenzenes. The metabolites from -1,2,3,4,5,6-hexachlorocyclohexene and -1,3,4,5,6-pentachlorocyclohexene are identified as 1,2,4-trichlorobenzene and 1,4-dichlorobenzene, respectively. ATP synthesis, converting these chlorinated compounds, is observed in the cell suspension of C. rectum as indicated by luciferase-luciferin reaction and phosphorylation of 32P-labeled phosphate. These observation lead to the conclusion that HCH and related compounds serve as artificial electron acceptors of the Stickland reaction, and therefore, the reductive dechlorination is associated with ATP synthesis.Abbreviations HCH

Summary In this paper, the results of the preceding electrophysiological study of sodium-alanine cotransport in pancreatic acinar cells are compared with kinetic models. Two different types of transport mechanisms are considered. In the simultaneous mechanism the cotransporterC forms a ternary complexNCS with Na+ and the substrateS; coupled transport of Na+ andS involves a conformational transition between statesNCS andNCS with inward- and outward-facing binding sites. In the consecutive (or ping-pong) mechanism, formation of a ternary complex is not required; coupled transport occurs by an alternating sequence of association-dissociation steps and conformational transitions. It is shown that the experimentally observed alanine- and sodium-concentration dependence of transport rates is consistent with the predictions of the simultaneous model, but incompatible with the consecutive mechanism. Assuming that the association-dissociation reactions are not rate-limiting, a number of kinetic parameters of the simultaneous model can be estimated from the experimental results. The equilibrium dissociation constants of Na+ and alanine at the extracellular side are determined to beK

of the dissociation constants of Na+ from the binary (NC) and the ternary complex (NCS) at the extracellular side is estimated to be <-6. This indicates that the binding sequence of Na+ andS to the transporter is not ordered. The current-voltage behavior of the transporter is analyzed in terms of charge translocations associated with the single-reaction steps. The observed voltage-dependence of the half-saturation concentration of sodium is consistent with the assumption that a Na+ ion that migrates from the extracellular medium to the binding site has to traverse part of the transmembrane voltage. 相似文献

Summary Evaporation of a solution of thymidine plus either theexo or theendo diastereomer of uridine cyclic 2,3-O, O-phosphorothioate (U > p(S) in 1,2-diaminoethane hydrochloride buffer gave the 2,5 and 3,5 isomers of (P-thio) uridylylthymidine (Up(S)dT) in a ratio of 1:2 with a combined yield of about 20%. These isomers were re-converted to U > p(S) and dT by a reaction that is known to proceed by an in-line mechanism. Both the 2,5 and 3,5 isomers gave as product the same diastereomer of U > p(S) that had been used originally in their formation. These dry-state prebiotic reactions (Verlander, Lohrmann, and Orgel 1973) are thus shown to be stereospecific, and both the 2,5 and 3,5 internucleotide bonds are formed by an in-line mechanism.Abbreviations DAE

Summary A restriction fragment of DNA carrying the P gene was cloned in the high copy number plasmid RSF2124. Cells harbouring this new plasmid RSF2124/E complement Pam80 phage. A lac promoter-operator region (lacP), produced by EcoRI digestion of plasmid pKB252, was inserted into RSF2124/glE such that induction of the lac promoter by IPTG or lactose leads to increased production of the P gene product. A high amount of P protein in E. coli cells results in a slow inhibition of bacterial DNA synthesis, suggesting that the initiation reaction is blocked by P protein. Synthesis of DNA proceeds normally under these conditions.Nonsuppressing groPA15 mutant bacteria which are unable to support the replication of wild-type (wt), acquire the ability to replicate Pam80 phage but not wt when they are transformed with a plasmid carrying the P gene. When harbouring a plasmid containing the mutant Pamber 80 gene, groPA15 mutants are able to support the replication of wt phage when infected at a high multiplicity. Pam80 phage does not multiply in these cells. 相似文献

Two intracellular -glucosidases (E.C. 3.2.1.21) were purified from the filamentous fungus Neurospora crassa, mutant cell-1 (FGSC no. 4335) and characterized. The extent of purification were 2.55- and 28.89-fold for -glucosidase A and -glucosidase B, respectively. -Glucosidase A was a dimeric protein, and B a monomeric protein, with molecular masses of 178 and 106 kDa, respectively. Both isoenzymes were glycoproteins with relatively high carbohydrate contents (-glucosidase A, 29.2%; -glucosidase B, 34.2%). The isoelectric points determined by IEF were 6.27 and 4.72, respectively. pH optima for activity were determined to be 5.0 and 5.5, and temperature optima to be 55 and 60 °C, for -glucosidases A and B, respectively. Both purified -glucosidases. especially -glucosidase B, showed relatively high stability against pH and temperature. Both enzymes were stable in the pH range of 5.0–9.0. The activities were completely retained up to 48 h at temperatures below 40 °C. At higher temperatures, enzymes were relatively unstable and lost their activities at 60 °C after 24 h. Both -glucosidases were highly activated by CuCl2, and inhibited by SnCl2 and KMnO4. Hg2+ and Ag+ also inhibited severely -glucosidase B. The K
m and V
max values of the isoenzymes against cellobiose as substrate were 1.50 mM and 12.2mol min–1 mg–1 for -glucosidase A and 2.76 mM and 143.5 mol min–1 mg–1 for -glucosidase B. 相似文献

Confidence interval estimators for heritability for several mating and experiment designs 总被引:1,自引:1,他引:0

Summary Confidence interval estimators have not been described for several heritability (H) estimators relevant to recurrent family selection. Previously described H interval estimators do not apply to onefactor mating designs in split-plot in time experiment designs in one or more locations, one-factor mating designs for several experiment designs in two or more locations and years, and two-factor mating designs for several experiment designs in two or more locations or years. Our objective was to derive H interval estimators for these cases. H reduced to a function of constants and a single expected mean square ratio in every case; H=1–E(M)/E(M) where E(M) is a linear function of expected mean squares and E(M) is a single expected mean square. It was shown that F=[M/E(M)]/[M/E(M)] has an approximate F-distribution with df and df degrees of freedom, respectively, where M and M are mean squares corresponding to E(M) and E(M), respectively. H is a function of F, therefore, we used F to define an approximate (1–) interval estimator for H.Oregon Agricultural Experiment Station Technical Paper No. 7923 相似文献

The present paper reports our attempts to determine whether the inclusion of 0.0014 mM Zn++ within a hydroponic culture medium affects the ability of 12-day-old Zea mays, cv. SS-522 to take-up [3H]-aflatoxin B1. Data from the corollary experiment, i.e., whether inclusion of aflatoxin affects the ability of Zea mays, cvs. Truckers White, X-Sweet and Merit to take-up 65ZnCl2 are presented also. This report is a preliminary to one regarding an in-progress analysis of whether pollutant levels of Zn++ affect aflatoxin uptake and distribution. In the absence of irrigating seedlings, which were grown in Perlite containing 65ZnCl2, with a solution containing mixed aflatoxins, the stem contained the greatest amount of label with root plus seed the next highest and the leaf the least for each of the cvs. In contrast, when the seedlings were irrigated with a solution containing mixed aflatoxins, the root plus seed contained either an amount nearly identical to (cv. Truckers White) or in excess of that within the stem (cvs. X-Sweet and Merit). Calculation of the percentages of aflatoxin-induced diminutions in leaf, stem and root label suggested that the aflatoxins interfered with the translocation of 65ZnCl2 from the root to the stem and leaf, at least for cvs X-Sweet and Merit. When 0.0014mM Zn++ as ZnSO4 was added to an incubation medium in which 12-day-old seedlings were suspended and plant growth assessed over 72 hours, a 15% increase (significant at 0.05 level) in seedling height over that of Zn++-deficient plants was observed. No differences in [3H]-aflatoxin B1 uptake were noted between those seedlings which were grown in either Zn++-containing or lacking media. Less than one % of the[3H]-aflatoxin B1 which was taken-up was recovered within chloroform extracts of the seedlings. The distributions of radioactivity from [3H]-aflatoxin B1 for leaf, stem, seed and root were 0, 57, 26 and 19% and 0, 26, 58 and 18% for Zn++-containing and -lacking media, respectively. 相似文献

The primary structure of the bglA gene region encoding a -glucosidase of Thermotoga maritima strain MSB8 was determined. The bglA gene has the potential to code for a polypeptide of 446 amino acids with a predicted molecular mass of 51545 Da. The T, maritima -glucosidase (BglA) was overexpressed in E. coli at a level comprising approximately 15–20% of soluble cellular protein. Based on its amino acid sequence, as deduced from the nucleotide sequence of the gene, BglA can be classified as a broad-specificity -glucosidase and as a member of the -glucosidase family BGA, in agreement with the results of enzymatic characterization of the recombinant protein. Comparative sequence analysis revealed distant amino acid sequence similarities between BGA family -glucosidases, a -xylosidase, -1,4-glycanases of the enzyme family F (mostly xylanases), and other families of -1,4-glycosyl hydrolases. This result indicates that BGA -glucosidases may comprise one enzyme family within a large enzyme order of retaining -glycosyl hydrolases, and that the members of these enzyme groups may be inter-related at the level of active site architecture and perhaps even on the level of overall three-dimensional fold. 相似文献

We investigated circadian ocular rhythms in the Japanese quail, Coturnix coturnix japonica. The birds were placed under light-dark cycles (LD 1212), constant light (LL) and constant darkness (DD), and the retinas were dissected out at four-hour intervals throughout 24 h. Following measurements were performed. (1) Melatonin content in the retina was measured by radioimmunoassay. It was low in light and several folds higher in darkness under LD 1212. The rhythm continued in DD, but disappeared in LL. (2) Mitotic figures in the corneal epithelium were counted. Similar rhythms to the melatonin content were observed in the corneal mitotic rate with a slight phase delay. (3) The retinas were fixed at 4-h intervals and immunostained with anti-bovine rhodopsin serum and anti-chicken iodopsin monoclonal antibodies. The outer segments of photoreceptor cells were stained intensively throughout 24 h in LD 1212, LL and DD. In contrast, the stainability of the locus close to the outer limiting membrane where the Golgi apparatus exists changed diurnally. Scores showing the ratio of cells with positive staining indicated high values from 4 h after the onset of light to the beginning of dark phase under LD 1212. The values were high throughout 24 h in LL and intermediate or low in DD. (4) To investigate the effect of melatonin on the corneal mitotic rate and visual pigments at the Golgi region, melatonin was injected into one eye and saline into the contralateral eye. Melatonin induced a phase advance in the corneal mitotic rate under LD 1212, but did not induce a rhythm under LL. The ratio of photoreceptor cells with positive staining to anti-visual pigment antibodies at the Golgi region was not affected by melatonin injection.Abbreviations

Rapid multiplication of axillary meristems and direct shoot development occurred from nodal explants of mature Eucalyptus tereticornis Sm. with 5.3 M NAA, 1.1 M IAA and 4.4 M BA in Murashige-Skoog medium. Repeated subcultures of the second generation shoot cultures into low cytokinin-auxin containing media (0.44–0.88 M BA+0.1 M NAA) yielded axillary microshoots in large numbers. Half-strength MS liquid medium with 4.9 M IBA, 5.5 M IAA and 5.3 M NAA for four days, half-strength semi-solid hormonefree MS medium with charcoal, and MS liquid medium without charcoal and hormones, in sequence, induced rooting of shoots in the dark. This system is suitable for the mass propagation of this difficult-to-root eucalypt.Abbreviations BA

Fish egg polysialoglycoprotein (PSGP) is a novel type of 200 kDa-glycoprotein containing more than 50% sialic acid by weight and about 90O-glycosidically-linked sialoglycan units per molecule. Of about 100 different molecular species assumed to be present in a sialoglycan mixture obtained by alkaline borohydride treatment ofSalvelinus leucomaenis pluvius PSGP, 23 mono- to tetrasialylglycans were isolated by anion-exchange chromatography and preparative column chromatography on porous silica, and their structures were determined. Core asialo-oligosaccharides were obtained from PSGP of four species of salmonid fishes by exhaustive enzymatic desialylation of sialoglycan mixtures and the structures of purified compounds were determined. Two complete types of asialopentasaccharide core structures, Fuc1-3GalNAc1-3Gal1-4 Gal1-3GalNAcOL, and GalNAc1-4GalNAc1-3Gal1-4Gal1-3GalNAcOL, and all of the possible biosynthetic precursors of these pentasaccharide cores were found in every PSGP examined. All types of oligosaccharide chains, both complete and incomplete, were found to occur in highly sialylated forms in PSGP.Abbreviations NeuAc

The reaction of methanol dehydrogenase with cytochrome c
L from Methylophaga marina and the reactions of the non-physiological substrates, Wurster's blue and ascorbic acid, with both proteins were studied as a function of temperature (4–32 °C), pressure (1–2000 bar) and ionic strength using the optical high pressure stopped-flow method. The thermodynamic parameters H, S and V were determined for all reactions where electron transfers are involved. These data allowed the determination of the Maxwell relationships which proved the internal thermodynamic consistency of the system under study. A conformational change on the cytochrome c
L level was deduced from both breaks in the Arrhenius plots and the variation of the V with temperature.Abbreviations MOPS

Summary According to the program Palynological Italian Flora, Aeropalynological section, the pollen morphological card ofPinus pinea L. is presented. The study is carried out on pollen coming from three Italian localities and regards fresh and acetolyzed pollen. For each sample, measurements are carried out on 30 fresh pollen grains in glicerol jelly with fuchsin and on 30 acetolyzed pollen grains in water/glicerol (1/1); general observations regard 1000 fresh and 1000 acetolyzed pollen grains/sample. Some observations on the main differences between fresh and acetolyzed pollen are mentioned.
