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.
