| metabolism of poly- -hydroxybutyrate: effect of mild alkaline extraction on native poly- -hydroxybutyrate granules. | mild alkaline extraction of native poly-beta-hydroxybutyrate (phb) granules results in the solubilization of a protein fraction. both the solubilized protein fraction and the extracted granules are essentially devoid of phb synthetase activity unless recombined. the protein fraction has been separated by chromatography into two components (a-i and a-ii). a-i but not a-ii can be recombined with extracted granules to give rise to phb synthetase activity. extracted granules no longer require pretre ... | 1971 | 5001870 |
| mutants of rhodospirrillum rubrum obtained after long-term anaerobic, dark growth. | rhodospirillum rubrum s(1) cells were grown for more than 100 generations under strict anaerobic, dark conditions in liquid medium with sodium pyruvate. during this time, growth became nonpigmented. when cells were streaked onto the surface of solid growth medium in anaerobic bottles and placed in the dark, a few light-red colonies developed, but the majority was nonpigmented. mutants were obtained from colonies selected on the basis of pigmentation and bacteriochlorophyll a content. the growth, ... | 1971 | 5003179 |
| temperature-sensitive mutations of the photosynthetic apparatus of rhodospirillum rubrum. | temperature-sensitive mutants of rhodospirillum rubum have been isolated by enrichment techniques selecting for conditionally aberrant electron flow in various portions of the electron transport scheme. the temperature sensitivity of a class of these strains is shown to preferentially affect the photosynthetic mode of growth and energy production over the aerobic mode. | 1971 | 5276284 |

| 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 |

| ribulose diphosphate carboxylase from autotrophic microorganisms. | thiobacillus denitrificans was grown anaerobically with nitrate as an acceptor in both sterile and nonsterile media. ribulose diphosphate carboxylase was stable throughout the exponential growth phase and declined slowly only after cells reached the stationary phase. reversible inactivation of the carboxylase occurred in extracts as a result of bicarbonate omission. the enzyme was purified 32-fold with excellent recovery of a preparation which was 50 to 60% pure by the criterion of polyacrylamid ... | 1972 | 4623310 |
| concerted feedback inhibition of the aspartokinase of rhodospirillum tenue by threonine and methionine: a novel pattern. | the presence of a single aspartokinase was demonstrated in rhodospirillum tenue. the enzyme has been purified about 60-fold. no physical association exists in this species between aspartokinase and homoserine dehydrogenase. the general properties of the enzyme are described. inhibition by l-lysine, by l-threonine, and concerted inhibition by these two end products are regulatory characters which have also been found in many other species. in r. tenue, aspartokinase is also subject to a hitherto ... | 1972 | 5079065 |

| studies on the light-dependent synthesis of inorganic pyrophosphate by rhodospirillum rubrum chromatophores. | characteristics of inorganic pyrophosphate synthesis from inorganic orthophosphate were examined in chromatophores of rhodospirillum rubrum. the application of an adp-glucose pyrophosphorylase-trapping system has shown in an unequivocal fashion that pyrophosphate is a product of a light-dependent reaction utilizing p(i) as the substrate. only very limited pyrophosphate synthesis takes place in the dark. the rates of synthesis of both atp and pyrophosphate were studied under conditions in which t ... | 1972 | 4345276 |

| the photoreduction of nicotinamide-adenine dinucleotide by chromatophore fractions from rhodospirillum rubrum. | the photoreduction of nicotinamide-adenine dinucleotide (nad(+)), catalyzed by chromatophore fractions from young (1 day) and old (4-5 days) cultures of rhodospirillum rubrum, was measured in the presence of either succinate or 2,6-dichlorophenol indophenol (dpip) and an excess of ascorbate. the time-course of photoreduction in the succinate system suggested a "reversed electron flow" from the donor to nad(+) mediated by a high energy intermediate produced by a light-induced, cyclic electron tra ... | 1972 | 4338746 |
