Poly(dA).poly(dT), but not B-form DNA, is specifically recognized by experimentally induced anti-kinetoplast or anti-poly(dA).poly(dT) immunoglobulins. Antibody binding is completely competed by poly(dA).poly(dT) and poly(dA).poly(dU) but not by other single- or double-stranded DNA sequences in a right-handed B-form. Antibody interaction with poly(dA).poly(dT) depends on immunoglobulin concentration, incubation time and temperature, and is sensitive to elevated ionic strengths. Similar conformations, for example, (dA)4-6 X (dT)4-6, in the kinetoplast DNA of the parasite Leishmania tarentolae are also immunogenic and induce specific anti-poly(dA).poly(dT) antibodies. These antibody probes specifically recognize nuclear and kinetoplast DNA in fixed flagellated kinetoplastid cells as evidenced by immunofluorescence microscopy. Anti-poly(dA).poly(dT) immunofluorescence is DNase-sensitive and competed by poly(dA).poly(dT), but not other classical double-stranded B-DNAs. Thus, these unique cellular B'-DNA helices are immunogenic and structurally similar to synthetic poly(dA).poly(dT) helices in solution.  相似文献

High activity of taurine:alpha-ketoglutarate aminotransferase was found exclusively in cell-free extracts of Achromobacter superficialis and A. polymorph. The former was chosen for characterization of the enzymatic reaction. The enzyme activity was enhanced by addition of beta-alanine to the growth medium. The product from alpha-ketoglutarate was identified as l-glutamate. Another product has been isolated, purified, and identified as sulfoacetaldehyde (2-oxoethanesulfonate), a deamination product from taurine, by comparison between the 2,4-dinitrophenylhydrazones of the synthetic and enzymatic products on the basis of studies by paper chromatography, by visible, infrared, and nuclear magnetic resonance spectrophotometries, and by elemental analysis. This enzymatic transamination was found to proceed stoichiometrically and reversibly as follows: NH(2).CH(2).CH(2).SO(3)H + HOOC.CH(2).CH(2).CO.COOH right harpoon over left harpoon OHC.CH(2).SO(3)H + HOOC.CH(2).CH(2).CH(NH(2)).COOH.  相似文献

The kinetics and mechanism of binding of Cu-(II).bleomycin, Fe(III).bleomycin, and Cu(II).phleomycin to DNA were studied by using fluorometry, equilibrium dialysis, electric dichroism, and temperature-jump and stopped-flow spectrophotometry. The affinity of Cu(II).bleomycin for DNA was greater than that of metal-free bleomycin but less than that of Fe(III).bleomycin. Cu(II).bleomycin exhibited a two-step binding process, with the slow step indicating a lifetime of 0.1 s for the Cu(II).bleomycin.DNA complex. Fe(III).bleomycin binding kinetics indicated the presence of complexes having lifetimes of up to 22 s. DNA was lengthened by 4.6 A/molecule of bound Cu(II).bleomycin and by 3.2 A/bound Fe(III).bleomycin but not at all by Cu(II).phleomycin, suggesting that both bleomycin complexes intercalate while the phleomycin complex does not. However, phleomycin exhibited nearly the same specificity of DNA base release as bleomycin. These results suggest that the coordinated metal ion plays a major role in the binding of metal-bleomycin complexes to DNA but that intercalation is neither essential for DNA binding and degradation nor primarily responsible for the specificity of DNA base release by these drugs.  相似文献

The rabbit antiserum against poly(I).poly(C) purified by hydroxyapatite column chromatography contained three distinct antibodies. They were fractionated into three antibody populations by a series of precipitations (with poly(A).poly(U), poly(I), and poly(I).poly(C)) and their specificities were examined by quantitative complement fixation, double diffusion tests and radioimmunoassay. The first population was common to the double helical structure of double-stranded RNAs. The second was specific for poly(I) and the third was specific for poly(I).poly(C). These studies demonstrated that specific antibodies exclusively reactive with poly(I).poly(C) existed in the rabbit antiserum against poly(I).poly(C).  相似文献

We have studied by gravimetric measurements and FTIR spectroscopy the hydration of duplexes and triplexes formed by combinations of dA(n), dT(n), rA(n), and rU(n) strands. Results obtained on hydrated films show important differences in their hydration and in the structural transitions which can be induced by varying the water content of the samples. The number of water molecules per nucleotide (w/n) measured at high relative humidity (98% R.H.) is found to be 21 for dA(n).dT(n) and 15 for rA(n).rU(n). Addition of a third rU(n) strand does not change the number of water molecules per nucleotide: w/n=21 for rU(n)*dA(n).dT(n) and w/n=15 for rU(n)*rA(n).rU(n). On the contrary, the addition of a third dT(n) strand changes the water content but in a different way, depending whether the duplex is DNA or RNA. Thus, a loss of four water molecules per nucleotide is measured for dT(n)*dA(n).dT(n) while an increase of two water molecules per nucleotide is observed for dT(n)*rA(n).rU(n). The final hydration is the same for both triplexes (w/n=17). The desorption profiles obtained by gravimetry and FTIR spectroscopy are similar for the rA(n).rU(n) duplex and the rU(n)*rA(n).rU(n) triplex. On the contrary, the desorption profiles of the dA(n).dT(n) duplex and the triplexes formed with it (rU(n)*dA(n).dT(n) and dT(n)*dA(n).dT(n)) are different from each other. This is correlated with conformational transitions induced by varying the hydration content of the different structures, as shown by FTIR spectroscopy. Modifications of the phosphate group hydration and of the sugar conformation (S to N type repuckering) induced by decrease of the water content are observed in the case of triplexes formed on the dA(n).dT(n) duplex.  相似文献

Under secondary metabolic conditions, the white-rot basidiomycete Phanerochaete chrysosporium degraded 2,7-dichlorodibenzo-p-dioxin (I). The pathway for the degradation of I was elucidated by the characterization of fungal metabolites and oxidation products generated by lignin peroxidase (LiP), manganese peroxidase (MnP), and crude intracellular cell-free extracts. The multistep pathway involves the degradation of I and subsequent intermediates by oxidation, reduction, and methylation reactions to yield the key intermediate 1,2,4-trihydroxybenzene (III). In the first step, the oxidative cleavage of the dioxin ring of I, catalyzed by LiP, generates 4-chloro-1,2-benzoquinone (V), 2-hydroxy-1,4-benzoquinone (VIII), and chloride. The intermediate V is then reduced to 1-chloro-3,4-dihydroxybenzene (II), and the latter is methylated to form 1-chloro-3,4-dimethoxybenzene (VI). VI in turn is oxidized by LiP to generate chloride and 2-methoxy-1,4-benzoquinone (VII), which is reduced to 2-methoxy-1,4-dihydroxybenzene (IV). IV is oxidized by either LiP or MnP to generate 4-hydroxy-1,2-benzoquinone, which is reduced to 1,2,4-trihydroxybenzene (III). The other aromatic product generated by the initial LiP-catalyzed cleavage of I is 2-hydroxy-1,4-benzoquinone (VIII). This intermediate is also generated during the LiP- or MnP-catalyzed oxidation of the intermediate chlorocatechol (II). VIII is also reduced to 1,2,4-trihydroxybenzene (III). The key intermediate III is ring cleaved by intracellular cell extracts to produce, after reduction, beta-ketoadipic acid. In this pathway, initial oxidative cleavage of both C-O-C bonds in I by LiP generates two quinone products, 4-chloro-1,2-benzoquinone (V) and 2-hydroxy-1,4-benzoquinone (VIII). The former is recycled by reduction and methylation reactions to generate an intermediate which is also a substrate for peroxidase-catalyzed oxidation, leading to the removal of a second chlorine atom. This unique pathway results in the removal of both aromatic chlorines before aromatic ring cleavage takes place.  相似文献

Poly(dG-dC).poly(dG-dC) was modified by the reaction with 4-hydroxyaminoquinoline 1-oxide (4HAQO) in the presence of seryl-AMP. The conformations of 4HAQO-modified poly(dG-dC).poly(dG-dC) and of poly(dG-dC).poly(dG-dC) were studied by circular dichroism spectra under various salt concentration conditions. 4HAQO residues to guanine bases are inefficient in inducing the transition of poly(dG-dC).poly(dG-dC) from B-form to Z-form conformation. We have elicited monoclonal antibodies against 4HAQO-poly(dG-dC).poly(dG-dC). They were characterized using enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA) and binding to supercoiled DNA. These antibodies reacted with 4HAQO-poly(dG-dC).poly(dG-dC) specifically but not with 4HAQO-modified DNA or poly(dG).poly(dC). However, they cross-reacted with N-acetoxy-2-acetylaminofluorene-modified poly(dG-dC).poly(dG-dC) in Z-form conformation. These monoclonal antibodies may recognize a unique conformation in poly(dG-dC).poly(dG-dC) after 4HAQO modification.  相似文献
