characterization of the deoxyribonucleic acid of various strains of halophilic bacteria.bacteria classified as extreme halophiles, in the genera halobacterium and halococcus, contain deoxyribonucleic acid (dna) which displays two components in a cscl equilibrium density gradient. the base composition of the major dna component ranges from 66 to 68% guanine plus cytosine (gc), whereas that of the satellite dna comprising some 11 to 36% of the total, is between 57 and 60% gc. purification of the bacterial cells in a cscl density gradient and other more conventional strain purificatio ...19694979441

control of delta-aminolaevulate synthetase activity in rhodopseudomonas spheroides.1. delta-aminolaevulate synthetase from rhodopseudomonas spheroides grown semi-anaerobically undergoes a spontaneous activation during the first hour after the disruption of cells when homogenates are stored at 4 degrees . 2. after cultures of r. spheroides growing semi-anaerobically are oxygenated no activation of delta-aminolaevulate synthetase occurs in cell extracts. cessation of activation in extracts is almost complete 10min. after oxygenation of cells has begun. 3. a heat-stable fraction ...19695774467

bacteriochlorophyll and heme synthesis in rhodopseudomonas spheroides: possible role of heme in regulation of the branched biosynthetic pathway.synthesis of heme, measured by incorporation of iron-59, and of bacteriochlorophyll was studied with wild-type and mutant strains of rhodopseudomonas spheroides. the wild type formed heme from glycine and succinate at one-fortieth the rate of bacteriochlorophyll under anaerobic-light conditions. added delta-aminolevulinate stimulated heme synthesis 10-fold without increasing bacteriochlorophyll production. heme synthesis from glycine and succinate was increased when the magnesium branch of the b ...19695784220
mutant strains of rhodopseudomonas spheroides lacking delta-aminolevulinate synthase: growth, heme, and bacteriochlorophyll synthesis.two mutant strains of rhodopseudomonas spheroides were described which lacked delta-aminolevulinate synthase activity. they required delta-aminolevulinate for growth; they did not respond to protoporphyrin or magnesium photoporphyrin, and only poorly to hemin. synthesis of cytochromes and heme by mutant h-4 was dependent upon delta-aminolevulinate; this strain did not form bacteriochlorophyll either with or without delta-aminolevulinate and, consequently, grew only under aerobic conditions. muta ...19695784221

the metabolism of aromatic compounds by rhodopseudomonas palustris. a new, reductive, method of aromatic ring metabolism.1. rhodopseudomonas palustris grows both aerobically and photosynthetically on aromatic acids. p-hydroxybenzoate and protocatechuate are able to support aerobic growth; these compounds are metabolized by the protocatechuate 4,5-oxygenase pathway. 2. the photoassimilation of benzoate and hydroxybenzoates and the effects of air and darkness on the photoassimilation of benzoate are described. 3. evidence in conflict with the pathway previously proposed for the photometabolism of benzoate is discuss ...19695807211

rhodopseudomonas acidophila, sp. n., a new species of the budding purple nonsulfur bacteria.a succinate-mineral salts medium of ph 5.2 provided selective enrichment conditions for rhodomicrobium vannielii and for a new species belonging to the athiorhodaceae, described herein as rhodopseudomonas acidophila. seven strains of the new species have been isolated from different sources in the united states and germany. the cells are rod-shaped or ovoid, 1.0 to 1.3 mum wide and 2 to 5 mum long, and motile by means of polar flagella. multiplication occurs by budding. the photopigments consist ...19695821103

reductive pentose cycle and formate assimilation in rhodopseudomonas palustris.rhodopseudomonas palustris assimilated formate autotrophically as carbon dioxide and hydrogen arising from the activity of the formic hydrogenlyase system. kinetic analyses of cell suspensions pulse-labeled with (14)c-formate or (14)c-bicarbonate showed similar distributions of incorporated radioactivity. in both cases phosphate esters were the first assimilation products. ribulose diphosphate carboxylase, phosphoribose isomerase, and phosphoribulokinase, characteristic enzymes of the reductive ...19695354954

energy flux and membrane synthesis in photosynthetic bacteria.synthesis of the energy-converting membrane complex of the photosynthetic purple bacterium rhodopseudomonas capsulata during growth under different conditions of energy flux was studied by examining the disorganizing effects of polymyxin b, with or without lysozyme, on integrity of the cell envelope. cells growing with a limited supply of energy show an elevated bacteriochlorophyll content and increased resistance to breakdown of the "permeability barrier" by these agents. it seems that purple b ...19694309249
multiple light-induced reactions of cytochromes b and c in rhodopseudomonas spheroides.illumination of chromatophore preparations from rhodopseudomonas spheroides causes the oxidation of a cytochrome c and a slight oxidation of a cytochrome b with a maximum at 560nm. when illuminated in the presence of antimycin a the oxidation of cytochrome c was more pronounced and cytochrome b(560) was reduced; the dark oxidation of cytochrome b(560) was biphasic in the presence of succinate, but not in the presence of nadh, a less effective reductant. split-beam spectroscopy showed that, in ad ...19694310060

age and fluorescence characteristics in some species of athiorhodaceae.nonsulfur photosynthetic bacteria (athiorhodaceae) exhibit a time-variable fluorescence in addition to a constant fluorescence. all species examined show upon aging a remarkable gain in the variable component at the expense of the constant component while the total fluorescence remains essentially invariant. this result can be rationalized by supposing a change in distribution of bacteriochlorophyll in photosynthetic units as cells age. alternatively, one may assume operation of two photochemica ...19695257017

the effect of redox potential on p870 fluorescence in reaction centers from rhodopseudomonas spheroides.we have prepared photosynthetic reaction centers from rhodopseudomonas spheroides and have studied the fluorescence of the photochemical electron donor, p870. the yield of this fluorescence rises at low redox potential, presumably because the photochemical electron acceptor becomes reduced and the photochemical utilization of excitation energy is then prevented. the redox titration curve for this increase in the fluorescence has a shape corresponding to the transfer of one electron. the midpoint ...196916591752

activation of delta-aminolaevulate synthetase in extracts of rhodopseudomonas spheroides.1. the spontaneous activation of delta-aminolaevulate synthetase in extracts from rhodopseudomonas spheroides grown semi-anaerobically in the light requires oxygen and does not take place anaerobically in the dark. 2. activation is completely prevented by azide or cyanide and is partially inhibited by chlorpromazine. these compounds inhibit markedly the succinoxidase activity of extracts. 3. nadh delays activation, but when it has been oxidized by the extract activation begins at the normal rate ...19704315934
