energy-linked reactions in photosynthetic bacteria. v. relation of the light-induced proton uptake to photophosphorylation in r. rubrum chromatophores.the kinetics of photophosphorylation have been studied in rhodospirillum rubrum chromatophores. no evidence for a time or intensity lag in photophosphorylation was found. an intensity lag could be induced with the uncoupling agent, m-chlorocarbonyl cyanide phenylhydrazone or, in some cases, by aging of the chromatophores. in chloroplasts, the occurrence of a time and intensity lag in phosphorylation has been correlated with the formation of a proton gradient and quoted as evidence that a proton ...19695257139
temperature-sensitive mutations of the photosynthetic apparatus of rhodospirillum rubrum.temperature-sensitive mutants of rhodospirillum rubum have been isolated by enrichment techniques selecting for conditionally aberrant electron flow in various portions of the electron transport scheme. the temperature sensitivity of a class of these strains is shown to preferentially affect the photosynthetic mode of growth and energy production over the aerobic mode.19715276284
