bacteriochlorophyll, fatty-acid, and protein synthesis in relation to thylakoid formation in mutant strains of rhodospirillum rubrum.mutant strains of rhodospirillum rubrum are isolated which are blocked in different stages of pigment synthesis. in these strains the morphogenesis of thylakoids and the pigment production are investigated. concerning bacteriochlorophyll synthesis two groups of mutants are separable. the members of the first group synthesize bacteriochlorophyll. some of these mutants excrete bacteriopheophytin. the strains of the second group are not able to synthesize bacteriochlorophyll. members of both groups ...19705438041

a novel sequence for phytoene dehydrogenation in rhodospirillum rubrum.differences between the absorption spectra of zeta-carotene (7,8,7',8'-tetrahydrolycopene) and the corresponding conjugated heptaene from diphenylamine-inhibited cultures of rhodospirillum rubrum have been rationalized by the identification of the latter compound as the unsymmetrical isomer, 7,8,11,12-tetrahydrolycopene. the structures of the other conjugated polyene hydrocarbons, phytoene, phytofluene and neurosporene, have been confirmed and a novel pathway for the dehydrogenation of phytoene ...19705411431
alternative pathways of spirilloxanthin biosynthesis in rhodospirillum rubrum.detailed studies of the properties of carotenoids isolated from diphenylamine-inhibited cultures of rhodospirillum rubrum have revealed a number of novel structures that indicate new features of carotenoid biosynthesis in the photosynthetic bacteria. both neurosporene and 7,8,11,12-tetrahydrolycopene undergo hydration, methylation and dehydrogenation to yield spheroidene and 11',12'-dihydrospheroidene respectively; all the intermediates in these pathways have been identified. these pathways repr ...19705411421

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.19715276284
energy-linked reactions in photosynthetic bacteria. v. relation of the light-induced proton uptake to photophosphorylation in r. rubrum chromatophores.the kinetics of photophosphorylation have been studied in rhodospirillum rubrum chromatophores. no evidence for a time or intensity lag in photophosphorylation was found. an intensity lag could be induced with the uncoupling agent, m-chlorocarbonyl cyanide phenylhydrazone or, in some cases, by aging of the chromatophores. in chloroplasts, the occurrence of a time and intensity lag in phosphorylation has been correlated with the formation of a proton gradient and quoted as evidence that a proton ...19695257139

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 ...19725079065

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, ...19715003179

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 ...19715001870

presence of rhapidosomes in various species of bacteria and their morphological characteristics.rod-shaped structures have been observed in cells of pseudomonas, photobacterium, proteus, and saprospira by use of the negative-contrast stain. these structures, referred to as rhapidosomes, appear to be normal components of these cells. other bacteria including escherichia, salmonella, shigella, klebsiella, micrococcus, bacillus, mycobacterium, rhodospirillum, and hydrogenomonas genera failed to reveal these structures. the rhapidosomes of saprospira were found to consist of two rods, one enca ...19674965198

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 ...19694887498
the nature, intergeneric distribution and biosynthesis of isoprenoid quinones and phenols in gram-negative bacteria.1. twenty-two aerobically grown gram-negative bacteria were analysed for demethylmenaquinones, menaquinones, 2-polyprenylphenols, 6-methoxy-2-polyprenylphenols and ubiquinones. 2. all the eight enterobacteria and both the two facultative organisms (aeromonas punctata and aeromonas hydrophila) examined contain all the compounds listed above. the principal homologues are octaprenyl; in addition lower (down to tri- or tetra-prenyl for the 2-polyprenylphenols) and sometimes higher homologues are als ...19694886765
