| sulfite reductase activity in extracts of various photosynthetic bacteria. | extracts of representative bacterial strains from the various families of photosynthetic prokaryotes are demonstrated to possess significant levels of sulfite reductase [ec 1.8.99.1; hydrogen-sulfide: (acceptor)oxidoreductase] activity with reduced methyl viologen as electron donor, but not nadph(2). the enzyme is localized primarily in the soluble fraction of the extracts, in contrast to adenylysulfate reductase [ec 1.8.99.2; amp, sulfite: (acceptor) oxidoreductase], which is bound normally in ... | 1974 | 4526215 |

| distribution of purple photosynthetic bacteria in wetland and woodland habitats of central and northern minnesota. | enrichment cultures for purple nonsulfur and sulfur photosynthetic bacteria were prepared from soil samples collected in central and northern minnesota. the purple nonsulfur bacteria were found in most wetland soils sampled but were uncommon in woodland and grassland soils. the ph range of the soils in which these bacteria occurred was 3.8 to 7.8, and the oxidation-reduction potential (e(h)) range was +510 to -65 mv. soils with a ph below 5.0 or an e(h) above +370 mv had few purple nonsulfur bac ... | 1974 | 4590487 |
| proteins of the inner membrane of escherichia coli: identification of succinate dehydrogenase by polyacrylamide gel electrophoresis with sdh amber mutants. | the inner or cytoplasmic membrane fraction of the cell envelope of escherichia coli was isolated by isopycnic centrifugation on sucrose gradients. the membrane proteins were analyzed by electrophoresis in sodium dodecyl sulfate-polyacrylamide gels (8.5%), and up to 56 bands were resolved. different preparations gave very similar patterns of proteins. succinate dehydrogenase mutants (sdh) were isolated which could not grow on succinate minimal medium, although growth on fumarate was unimpaired. t ... | 1974 | 4591960 |

| nitrogen fixation by rhodospirillum rubrum grown in nitrogen-limited continuous culture. | cell-free extracts of the photosynthetic bacterium rhodospirillum rubrum were inconsistent in reducing n(2). an internally illuminated fermentor, designed for the continuous culture of this organism on n(2) under nitrogen-limited conditions, produced cells which yielded cell extracts with consistent activity for cell-free n(2) fixation. a nitrogen-limited continuous culture, supplied ammonia rather than n(2), gave cell-free extracts with even more active n(2) fixation. extracts of cells grown in ... | 1969 | 4887498 |
