Intracellular location of enzymes in rhodopseudomonas spheroides.
By differential centrifugation of extracts of pigmented Rhodopseudomonas spheroides a number of constituents, phospholipid and lipid ornithine, and enzymes, zinc protoporphyrin chelatase, succinic dehydrogenase and S-adenosylmethionine-magnesium protoporphyrin methyltransferase, have been found to be associated both with chromatophores and with non-pigmented particulate material. These componen...
متن کاملElectron microscopy of chromatophores of Rhodopseudomonas spheroides.
Gibson, K. D. (St. Mary's Hospital Medical School, London, England). Electron microscopy of Rhodopseudomonas spheroides. J. Bacteriol. 90:1059-1072. 1965.-Fixed and stained chromatophores and whole cells of anaerobically grown Rhodopseudomonas spheroides were examined in thin sections in the electron microscope. Both purified chromatophores and intracellular membrane-bound vesicles had exactly ...

Bacteriol. 89:697-705. 1965.-Particulate enzyme preparations of cell extracts of Rhodopseudomonas spheroides possess constitutive dehydrogenase and oxidase activities for aldose sugars, reduced nicotinamide adenine dinucleotide (NADH(2)),...
متن کاملProtochlorophyll-like Pigment Produced by Rhodopseudomonas spheroides
The identification of intermediates in the biosynthesis of chlorophyll has been largely dependent upon the use ofmutants of Chlorella that are unable to synthesize chlorophyll but accumulate in the medium various tetrapyrrole compounds assumed to be precursors (for a review see Granick & Mauzerall, 1961). In particular, Granick (1950) identified magnesium vinylphaeoporphyrin a5 monomethyl ester...
متن کاملThe effect of adenosine triphosphate on porphyrin excretion and on glycine metabolism in Rhodopseudomonas spheroides.
1. ATP, GTP, CTP and UTP at concentrations of 1mm markedly decrease the amount of coproporphyrin excreted by Rhodopseudomonas spheroides illuminated in a medium containing glycine, succinate and fumarate. 2. The effect of ATP is decreased if ethionine is also added to the medium. 3. Evidence is presented showing that ATP is taken up by the organisms from the medium. 4. ATP is shown to have a ma...
