There is a lack of tools to analyze simulations of protein molecular dynamics quantitatively. Our aim is to use calmodulin, a prototypical calcium-binding protein, to describe a strategy and some tools for extracting relevant information from dynamics calculations. Our main conclusions are as follows:
- •• Autocorrelation vectors may be used to represent a 3D conformation in an n-dimensional space, where n is variable (n ⩽ 20–30).
- •• On such a transformation, classic statistical tools (PCA, clustering, etc.) may be used to differentiate or characterize dynamics trajectories quantitatively.
- •• TSAR, an integrated package used for quantitative structure-activity relationships, is well suited (after minor modifications) for such a purpose.

- 1.1. A specific and sensitive sandwich enzyme-linked immunosorbent assay (ELISA) was developed for the measurement of low levels of serum immunoglobulin M (IgM) of chum salmon Oncorhynchus keta.
- 2.2. In this assay, 5 μl serum was enough to measure the concentration of IgM and the minimum detectable concentration of serum IgM was about 5 ng/ml.
- 3.3. Coefficients of variation within and between assays ranged from 2.90 to 9.61%.
- 4.4. IgM concentrations remained at low level (< 300 ng/ml) until 40 days after hatching and then increased rapidly at the period of emergence (48 days after hatching).

- 1.1. The sperm-agglutinating factor (SAF) could be induced in the serum of male Nile tilapias, Oreochromis niloticus, by injection of allogeneic sperm.
- 2.2. Only one class of molecules was demonstrated to be SAF in the serum.
- 3.3. Analysis on purified SAF revealed it to be a tetrameric molecule of IgM with a mol. wt of 760kD.
- 4.4. Cross reaction of the IgM with sperm of other teleost species suggests that sperm-specific surface antigens may be in evolution.

- 1.1. Six different monoclonal IgG mouse antibodies to heparin lyase I from Flavobacterium heparinum were prepared.
- 2.2. The monoclonal antibodies were used to detect heparin lyases I, II and III by dot-blotting immunoassay and by Western blotting.
- 3.3. Individual antibodies showed different reactivity toward the three heparin lyases.
- 4.4. The reactivity of two of the monoclonal antibodies was destroyed by exposing heparin lyases to sodium dodecyl sulfate.
- 5.5. The antibodies can be used to rapidly distinguish between the three heparin lyases.

- 1.1. An antiserum raised against a 14kDa β-galactoside specific lectin from human brain (HBL14) was used to probe blots from samples of serum and cerebrospinal fluid. The only HBL14-immunoreactive material detected was heavy and light chains of a β-galactoside-binding IgG fraction (lectin-like IgG).
- 2.2. Lectin-like IgG, as well as IgG Fab fragments, compete with HBL14 for binding either to anti-HBL14 antibody or to a lactosyl polyacrylamide-based copolymer.
- 3.3. Purification of lectin-like IgG was obtained by affinity chromatography on immobilized rabbit anti-lectin immunoglobulins. The carbohydrate-binding specificity of the purified molecules was restricted to β-Gal-containing structures and close to the HBL14 one.

- 1.1. To characterize an enzyme which metabolizes retinal in liver microsomes, several properties of the enzymatic reaction from retinal to retinoic acid were investigated using rabbit liver microsomes.
- 2.2. The maximum pH of the reaction in the liver microsomes was 7.6.
- 3.3. The Km and Vmax values for all-trans, 9-cis and 13-cis-retinals were determined.
- 4.4. The reaction proceeded in the presence of NADPH and molecular oxygen.
- 5.5. The incorporation of one atom of molecular oxygen into retinal was confirmed by using oxygen-18, showing that the reaction comprised monooxygenation, not dehydrogenation.
- 6.6. The monooxygenase activity was inhibited by carbon monoxide, phenylisocyanide and antiNADPH-cytochrome P-450 reductase IgG, but not by anti-cytochrome b5 IgG.
- 7.7. The enzymatic activity inhibited by carbon monoxide was photoreversibly restored by light of a wavelength of around 450 nm.
- 8.8. The retinal-induced spectra of liver microsomes with three isomeric retinals were type I spectra.
- 9.9. The microsomal monooxygenase activity induced by phenobarbital or ethanol were more effective than that by 3-methylcholanthrene, clotrimazole or β-naphthoflavone.
- 10.10. These results showed that the monooxygenase reaction from retinal to retinoic acid in liver microsomes is catalyzed by a cytochrome P-450-linked monooxygenase system.

- 1.1. Neonatal mice received subcutaneous injections of buffer, thiourea (TU) or propylthiouracil (PTU).
- 2.2. The PTU-treated mice were sacrificed on postnatal day 14 (P14) and the TU-treated mice on P28.
- 3.3. Brain weights of the TU- and PTU-treated mice were not significantly different from the controls.
- 4.4. Acid but not alkaline phosphatase activity in the braistem decreased after TU and PTU treatment.
- 5.5. Myelination as indicated by intensity of luxol fast blue staining was weaker in drug-treated animals.
- 6.6. The level of myelin marker enzyme, 2′,3′-cyclic nucleotide 3′-phosphohydrolase, was lower in the brainstem of PTU-treated animals.
- 7.7. The results suggest a correlation between acid phosphatase but not alkaline phosphatase activity with myelination in the developing mouse brain.

- 1.1. The oxygen consumption of crabs in normoxic and hypoxic (50% O2) seawater was measured directly after collection.
- 2.2. The influences of size and lunar cycles were removed by scaling the data.
- 3.3. Strong negative correlations between low individual levels of O2 consumption and the ability to compensate for hypoxia were apparent in Wicklow (subtidal) crabs.
- 4.4. Compensation for hypoxia was much greater on the flood tide than on the ebb.
- 5.5. Crabs from Roscoff (intertidal) had lower levels of compensation than those from Wicklow.
- 6.6. Size, sex and condition had no apparent effect upon these relationships.
- 7.7. Crabs acclimated to laboratory conditions have not shown this tidal variation in compensation for hypoxia.

- 1.1. Fundamental chitin digestion characteristics of Crassostrea virginica crystalline style were investigated.
- 2.2. Optimum temperature and pH were 34°C and 4.8. respectively.
- 3.3. The colloidal regenerated chitin (0.56mol/0.5 ml: GlcNAc equivalents) was saturating under all enzyme levels encountered.
- 4.4. There was no evidence of end product inhibition, even after 100 hr incubation.
- 5.5. Calculated Km for the chitinase complex was 1.19mM when determined using a 30 min assay, but was only 0.70 mM when determined using a 4.6 hr assay.
- 6.6. Both Km values are lower than reported for similar assays in other molluscs and for most bacteria.
- 7.7. Effect of substrate preparation on the kinetics are discussed.
- 8.8. Eight peaks of chitinase activity were resolved by DEAE-Fractogel ion exchange chromatography.

- 1.1. To understand the physiological roles of the 90-kDa stress protein (HSP90), we investigated the heparin- and antibody-binding domains of the protein.
- 2.2. For heparin-binding sites, HSP90 was digested completely with trypsin, and the digests were applied to a heparin-Sepharose column and eluted with 1.0 M NaCl, followed by 8.0 M urea.
- 3.3. Each elutant was purified by a reverse-phase C18 column.
- 4.4. Two peptides from the NaCl-eluted fraction and no peptide from the urea-eluted fraction were purified.
- 5.5. The purified peptides were sequenced by an automated peptide sequencer.
- 6.6. One of the heparin-binding sites was present between Leu-362 and Arg-365; another was present between Leu-645 and Lys-648.
- 7.7. These two peptides were basic and considerably hydrophilic.
- 8.8. For antibody-binding sites, HSP90 was mildly digested with trypsin, electrophoresed on SDS-polyacrylamide gels and transferred to PVDF membranes.
- 9.9. The four bound of the trypsin fragments could be sequenced with a peptide sequencer.
- 10.10. There was only one antibody-binding peptide, 38 kDa, starting from Pro-2. The others showed no cross-reactivity with the antibody and started from Leu-283.
- 11.11. Therefore, the epitopes of HSP90 are present between Pro-2 and Leu-282.
- 12.12. The heparin-binding sites are present from the middle region of the HSP90 molecule, and the antigen sites are at the N-terminal domain.
