| composition of the sulfur particle of chromatium vinosum strain d. | sulfur particles were isolated from the purple sulfur photosynthetic bacterium, chromatium vinosum strain d. the composition of these particles was determined to be 93% sulfur, 5% protein, and 0.6% lipid. gel electrophoresis indicated the presence of a single protein species with a molecular weight of 13,500 daltons. from these results, the sulfur particle is postulated to be bounded by a membrane consisting entirely of protein. | 1971 | 4323293 |

| biocarbonate effect on the photophosphorylation catalyzed by chromatophores isolated from chromatium strain d: xii. structure and function of chloroplast proteins. | photophosphorylation catalyzed by chromatophores prepared from chromatium strain d was stimulated by bicarbonate. the stimulative effect was ph dependent and the lower the ph the more marked the activation. at ph 8.0, bicarbonate (8 mm) exhibited a negligible effect, whereas at ph 7.0 approximately a 5-fold activation was observed. the apparent activation constant of bicarbonate was determined to be approximately 10.2 mm, at which concentration approximately a 7-fold activation of photophosphory ... | 1972 | 16658218 |
