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 ...

Electron donors to photo-oxidized reaction centers were studied in Rhodopseudomonas palustris and Rhodopseudomonas acidophila using whole cells, membrane preparations and reaction center-B880 complexes. In Rps. palustris, no hemes were tightly bound to the reaction center complex and cytochrome c2 was presumed to be the direct electron donor to the ...

The fine structure of Rhodopseudomonas acidophila
Canadian Journal of Microbiology, 1974The morphology of the photosynthetic bacterium Rhodopseudomonas acidophila strain P18aF1 1.2 has been investigated with the electron microscope. The cells grow by budding, the sessile buds eventually separating from the mother cells by constriction. In some dividing stages a belt-like structure was observed in the zone of division.

Anaerobic utilization of phenanthrene by Rhodopseudomonas palustris
Biotechnology Letters, 2011A phenanthrene-utilizing bacterium was anaerobically isolated and identified as Rhodopseudomonas palustris. It tolerated up to 100 mg phenanthrene l(-1) and degraded 50% of 50 mg phenanthrene l(-1) over 10 days. The presence of phenanthrene caused a prolonged lag phase (2-3 days) in cell growth and affected the photopigments biosynthesis, while DMSO ...

Carotenoid pigment conversion in rhodopseudomonas spheroides
Biochimica et Biophysica Acta, 1962Abstract 1. 1. The specific oxidation of the carotenoid pigment Spheroidene to Spheroidenone when anaerobic cultures of Rhodopseudomonas spheroides are aerated, has been studied. 2. 2. The conversion of Spheroidene to Spheroidenone is enhanced by light and reversibly inhibited by CO. Cyanide and chloramphenicol do not affect conversion. 3.
