| glycine decarboxylase in rhodopseudomonas spheroides and in rat liver mitochondria. | 1. glycine decarboxylase and glycine-bicarbonate exchange activities were detected in extracts of rhodopseudomonas spheroides and in rat liver mitochondria and their properties were studied. 2. the glycine decarboxylase activity from both sources is stimulated when glyoxylate is added to the assay system. 3. several proteins participate in these reactions and a heat-stable low-molecular-weight protein was purified from both sources. 4. these enzyme activities increase markedly when r. spheroides ... | 1970 | 5476725 |

| ferrochelatase of rhodopseudomonas spheroides. | extracts of rhodopseudomonas spheroides contain two ferrochelatases: one is soluble and forms metalloporphyrins from deuteroporphyrin and haematoporphyrin; the other is particulate and forms metalloporphyrins from protoporphyrin, mesoporphyrin, deuteroporphyrin and haematoporphyrin. neither enzyme incorporates mg(2+) into porphyrins or fe(2+) into porphyrin cytochrome c. by using the particulate enzyme, plots of 1/v versus 1/s when one substrate was varied and the other kept constant showed that ... | 1970 | 5500305 |

| effect of streptomycin on lipid composition with particular reference to cyclic depsipeptide biosynthesis in serratia marcescens and other micro-organisms. | the addition of low concentrations of streptomycin (5-10mug/ml of medium) to serratia marcescens caused significant alterations in the lipid composition of this organism, but neither growth nor pigmentation was affected. the acetone-soluble cyclic depsipeptides, which comprise on average 15% of the total lipid, were decreased almost to zero and the total lipid phosphorus was more than doubled in the presence of streptomycin. most of the phospholipid increase was due to an increase in phosphatidy ... | 1970 | 4923921 |

| role of phosphorylation coupling factor in light-dependent proton translocation by rhodopseudomonas capsulata membrane preparations. | the activity of the light-dependent proton pump (in the absence of phosphorylation substrates) of rhodopseudomonas capsulata "membrane vesicles," in contrast to that of chloroplasts, is not appreciably affected by detachment of phosphorylation coupling factor(s). proton uptake by such "uncoupled" (low phosphorylation activity) preparations is also unaffected by the addition of phosphorylation substrates (adp + arsenate + mg(2+)). the h(+) pump of "coupled" preparations, however, is stimulated wh ... | 1970 | 5002093 |

| chloroplast structure of the cryptophyceae. evidence for phycobiliproteins within intrathylakoidal spaces. | selective extraction and morphological evidence indicate that the phycobiliproteins in three cryptophyceaen algae (chroomonas, rhodomonas, and cryptomonas) are contained within intrathylakoidal spaces and are not on the stromal side of the lamellae as in the red and blue-green algae. furthermore, no discrete phycobilisome-type aggregates have thus far been observed in the cryptophyceae. structurally, although not necessarily functionally, this is a radical difference. the width of the intrathyla ... | 1971 | 5543400 |

| mutant of rhodopseudomonas spheroides unable to grow aerobically. | we isolated a mutant of rhodopseudomonas spheroides that grows normally under photosynthetic conditions but is unable to grow exponentially under aerobic conditions. photosynthetically grown cultures of the mutant increase in mass and cell number for about 10 hr after transfer to aerobic conditions. during this time, no heme pigments are synthesized and the q(o(2)) declines. in the mutant, synthesis of heme pigments is obligatorily coupled to synthesis of bacteriochlorophyll. | 1971 | 5557591 |

| interchangeability of phosphorylation coupling factors in photosynthetic and respiratory energy conversion. | the nonsulfur purple photosynthetic bacterium rhodopseudomonas capsulata can obtain energy for growth either by anaerobic photophosphorylation or dark oxidative (aerobic) phosphorylation. successful resolution of phosphorylation coupling factors from energy-converting membranes of this bacterium permitted tests for reciprocal function of such protein factors in oxidative-and photophosphorylation processes. evidence was obtained for the interchangeability of coupling factor preparations from dark ... | 1971 | 4398683 |

| deficiencies of chromatophore proteins in some mutants of rhodopseudomonas spheroides with altered carotenoids. | chromatophore proteins of a wild type and three mutant strains of rhodopseudomonas spheroides were examined by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. the mutants consisted of a green and a blue-green one, whose phenotypes were essentially the same as those of known mutants, and a brown one, which may be a double mutant and represents a new phenotype. wild-type chromatophores contained at least six major and seven minor protein bands, with molecular weights ... | 1971 | 4323296 |

| catalytic properties and regulatory diversity of inorganic pyrophosphatases from photosynthetic bacteria. | soluble inorganic pyrophosphatases of five species of nonsulfur purple bacteria were investigated in respect to reaction kinetics, regulatory behavior, and other characteristics. the enzymes appear to fall into two groups with correlated properties. the pyrophosphatases of rhodopseudomonas capsulata and r. spheroides have molecular weights of approximately 60,000, are stabilized by co(2+), and exhibit simple michaelis-menten reaction kinetics. on the other hand, the enzymes of r. palustris, r. g ... | 1971 | 4333319 |

| mutational and physiological enhancement of photosynthetic energy conversion in rhodopseudomonas capsulata. | photosynthetic growth of rhodopseudomonas capsulata, a nonsulfur purple bacterium, is severely inhibited by inorganic arsenate when this anion is present equimolar to orthophosphate in the culture medium. studies on an arsenate-resistant mutant indicate that its resistance can be explained by a significantly increased photophosphorylation capacity of the energy-converting machinery, which can compensate for the decrease in adenosine triphosphate regeneration rate caused by esterification of arse ... | 1971 | 5288777 |

| bacteriochlorophyll synthesis and the ultrastructure of wild type and mutant strains of rhodopseudomonas spheroides. | the ultrastructure of sectioned cells of mutant and wild type rhodopseudomonas spheroides has been examined by electron microscopy. the characteristic vesicles associated with the presence of bacteriochlorophyll were found in wild type cells grown with low aeration. these were also found in mutant ta-r which forms bacteriochlorophyll under high aeration. none of the mutants with blocks in bacteriochlorophyll synthesis contained intracytoplasmic membrane. these included mutant 8-17 which accumula ... | 1972 | 16658255 |
| phytol and bacteriochlorophyll synthesis in rhodopseudomonas spheroides. | phytol has been separated and identified in the unsaponifiable lipid fraction from wild type rhodopseudomonas spheroides, but it was not detected in mutant strains blocked at various stages of bacteriochlorophyll synthesis. incorporation of (14)c-acetate into phytol paralleled bacteriochlorophyll synthesis in suspensions of the wild type incubated anaerobically in the light. the addition of chloramphenicol inhibited both processes. it is concluded that phytol formation is tightly coupled to the ... | 1972 | 16658256 |

| biochemical physiology of a respiration-deficient mutant of the photosynthetic bacterium rhodopseudomonas capsulata. | nonsulfur purple photosynthetic bacteria generally possess the adaptive capacity to grow anaerobically (photosynthetically) and aerobically in darkness (energy obtained by respiratory phosphorylation). to develop a test system for study of interactions between the photosynthetic energy-conversion and dark respiration systems and the mechanism by which o(2) inhibits bacteriochlorophyll synthesis, we have isolated a mutant of rhodopseudomonas capsulata that is incapable of dark aerobic growth. bot ... | 1972 | 4337246 |

| coproporphyrinogenase activities in extracts of rhodopseudomonas spheroides and chromatium strain d. | 1. the anaerobic coproporphyrinogenase activity in an extract of rhodopseudomonas spheroides is inhibited by 1,10-phenanthroline, alphaalpha'-bipyridyl, flavins, 2,4-dinitrophenol and 1,4-naphthaquinone. these compounds have no effect on the aerobic coproporphyrinogenase activity. 2. on removal of small-molecular-weight material from a crude extract, the anaerobic system becomes very unstable; it can be stabilized by adding succinate. now nicotinamide nucleotides, in addition to mg(2+), atp and ... | 1972 | 4345352 |
