title: Interchangeability of phosphorylation coupling factors in photosynthetic and respiratory energy conversion.
abstract: The nonsulfur purple photosynthetic bacterium Rhodopseudomonas capsulata can obtain energy for growth either by anaerobic photophosphorylation or dark oxidative (aerobic) phosphorylation. Successful resolution of phosphorylation coupling factors from energy-converting membranes of this bacterium permitted tests for reciprocal function of such protein factors in oxidative-and photophosphorylation processes. Evidence was obtained for the interchangeability of coupling factor preparations from dark-grown and photosynthetically grown cells in both kinds of energy conversion.
