Changes in ribonucleic acid turnover during aerobic and anaerobic growth in Rhodopseudomonas spheroides.
Differences in the rate and extent of degradation of ribonucleic acid (RNA) labeled by a 30-sec pulse in aerobically or anaerobically grown Rhodopseudomonas spheroides have been studied by using rifampin to block RNA synthesis. In anaerobic cultures, unstable RNA is degraded with a half-life of 1.25 to 2.0 min, and about 40% of the pulse-labeled RNA is stable. In aerobic cultures, the half-life...
متن کاملExpansion of the 16S and 23S Ribosomal RNA Mutation Databases
The Ribosomal RNA Mutation Databases (16SMDB and 23SMDB) provide lists of mutated positions in 16S and 23S ribosomal RNA from Escherichia coli and the identity of each alteration. Information provided for each mutation includes: (i) a brief description of the phenotype(s) associated with each mutation; (ii) whether a mutant phenotype has been detected by in vivo or in vitro methods; and (iii) r...
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 ...
متن کاملIntracellular 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...
