observations on the bisulfite reductase (p582) isolated from desulfotomaculum nigrificans.the bisulfite reductase (p582) from desulfotomaculum nigrificans was purified to homogeneity as judged by polyacrylamide gel electrophoresis. by colorimetric methods of analysis, the products of bisulfite reduction by this enzyme were determined to be trithionate, thiosulfate, and sulfide. of these, trithionate was consistently found to be the major product, whereas the latter two were formed in lesser quantities. when [(35)s]bisulfite was incorporated as substrate, no labeled sulfide was detect ...19744424068
phospholipid composition of desulfovibrio species.the phospholipids of desulfovibrio desulfuricans, norway strain, d. vulgaris, and d. gigas were examined in relationship to their qualitative and quantitative composition. d. desulfuricans and d. vulgaris exhibited an essentially identical phospholipid composition consisting of phosphatidylethanolamine, phosphatidylglycerol, cardiolipin, and lysophosphatidylserine. phosphatidylserine (10.9%) was present in d. desulfuricans but was not detected in d. vulgaris. d. gigas was found to contain only t ...19744436257

sulfate reduction by a desulfovibrio species isolated from sheep rumen.several dissimilatory, sulfate-reducing bacteria were isolated from the rumen fluid of sheep fed purified diets containing sulfate. one isolate, strain d, was selected for characterization. this organism is a nonsporeforming, obligately anaerobic, mesophilic, nonmotile, gram-negative, straight rod. cell-free extracts show absorption maxima for cytochrome c(3) and desulfoviridin, characteristic of desulfovibrio. carbohydrates, as a sole carbon source, will support growth. lactate supports growth ...19744472525
structure of the oxidized form of a flavodoxin at 2.5-angstrom resolution: resolution of the phase ambiguity by anomalous scattering.flavodoxin from desulfovibrio vulgaris crystallizes in the oxidized form as well-formed, tetragonal bipyramids, space group p4(3)2(1)2, unit-cell parameters, a = b = 51.6 a, c = 139.6 a, 8 molecules per unit cell. the structure has been determined at 2.5-a resolution with phases based on a single isomorphous derivative. the phase ambiguity of a single derivative was resolved by use of anomalous scattering from the single-site sm(+3). the molecule has a five-strand pleated sheet core with two lon ...19724508313
structure of the radical form of clostridial flavodoxin: a new molecular model.interpretation of a new electron-density map at 3.25-a resolution has led to a somewhat revised model for the free radical (semiquinone) structure of flavodoxin from clostridium mp. although the general conformation of the molecule is very similar to that of oxidized desulfovibrio vulgaris flavodoxin, flavin mononucleotide-protein interactions are not identical in the two flavodoxins. in the cl. mp semiquinone molecule, the isoalloxazine ring appears to retain the essentially planar conformation ...19724508314
the binding of riboflavin-5'-phosphate in a flavoprotein: flavodoxin at 2.0-angstrom resolution.the crystal structure of the oxidized form of flavodoxin from desulfovibrio vulgaris has been studied at 2.0-a resolution, and a detailed description of the region around the flavin mononucleotide binding site is now available. the flavin is between a tyrosine group, roughly parallel to it on one side, and a tryptophan, about 45 degrees from being parallel, on the other side. the two carbonyl groups and two nitrogen atoms of the flavin are hydrogen bonded to the peptide chain of the protein, whi ...19734521211
