Catabolism of glycine in Rhodopseudomonas spheroides
Biochimica et Biophysica Acta, 1962Abstract Catabolism of glycine in Rhodopseudomonas spheroides grown anaerobically in the light was studied under various conditions. Under dark-aerobic conditions, formation of 14CO2 from [1-14C] and [2-14C]glycine was inhibited strongly by 5·10−5M sodium fluoroacetate.

Nitrogen assimilation in Rhodopseudomonas acidophila
Archives of Microbiology, 1978Rhodopseudomonas acidophila strain 7050 assimilated ammonia via a constitutive glutamine synthetase/glutamate synthase enzyme system. Glutamine synthetase had a Km for NH+4 of 0.38 mM whilst the nicotinamide adenine dinucleotide linked glutamate synthase had a Km for glutamine of 0.55 mM. R.

Membrane lipids of Rhodopseudomonas viridis
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1997In search of the precyanobacterial origin of the typical thylakoid lipids found in cyanobacteria and chloroplasts, we analyzed the polar lipids of the anaerobic phototrophic bacterium Rhodopseudomonas viridis. Glycolipids (monogalactosyl-, digalactosyl- and glucuronosyl diacylglycerol), phospholipids (phosphatidyl choline, -ethanolamine, -glycerol and ...

Adaptation of Rhodopseudomonas spheroids
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1968Abstract The composition of Rhodopseudomonas spheroides grown under oxygen or under air in the dark, or semi-anaerobically in the light was studied. The amounts of various constituents were expressed per cell. Anaerobically grown cells were 20 % lighter than cells grown under oxygen but contained approximately 50 % more protein and 85

[Isolation and identification of Rhodopseudomonas viridis and Rhodopseudomonas sulfoviridis].
Wei sheng wu xue bao = Acta microbiologica Sinica, 1995Under selective culture conditions, two pure cultures (strain G and strain SG) of the purple nonsulfur photosynthetic bacteria containing bacteriochlorophyll b were isolated from pulp effluent and sludge of sewage treatment plant by means of agar shake dilution.

Porphobilinogenase from Rhodopseudomonas palustris
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19891. Porphobilinogenase (PBGase) from Rp. palustris has been isolated and some properties of a partially purified fraction were studied. 2. PBGase has an optimum pH of 7.4 when activity was expressed in terms of porphyrins formed and two pH maxima at 7.4 and 8.5 when activity was based on the amount of PBG consumed. 3.

THE ESTABLISHMENT OF MITOCHONDRIA: PARACOCCUS AND RHODOPSEUDOMONAS
Annals of the New York Academy of Sciences, 1981Many aerobic bacteria (both facultative and obligate) possess a number of those biochemical features of mitochondria which are concerned with energy metabolism. However, only restricted number, notably Paracoccus denitrificans and Rhodopseudomonas spheroides, have the majority of these features.

The ADPglucose pyrophosphorylases from Rhodopseudomonas sphaeroides and Rhodopseudomonas gelatinosa are activated by fructose-6-phosphate, pyruvate and fructose-1,6 biophosphate-P2. The effects of the activators are to increase significantly the Vmax of ADPglucose synthesis and to lower the S0.5 values (concentration of substrates giving 50% maximal ...

From polluted water of a lagoon pond a new type of denitrifying photosynthetic purple bacteria was isolated. With respect to morphology, fine structure, photopigments, requirement for growth factors, the range of utilization of organic substrates for phototrophic growth and DNA base ratio, the denitrifying strains show the closest resemblance to ...

Monospecific antibodies have been prepared against cytochrome c2 from Rhodopseudomonas spheroides and Rhodopseudomonas capsulata, and against cytochrome c' from Rps. capsulata. These antibodies precipitated their respective antigens, but did not cross react with a wide range of procaryotic or eucaryotic cytochromes, or with other bacterial proteins ...
