A comparison of the constituent polypeptides of the B-800--850 light-harvesting pigment-protein complex from Rhodopseudomonas sphaeroides

Abstract

The polypeptide composition of the B-800-850 light-harvesting pigment-protein complex from Rhodopseudomonas sphaeroides has been determined. The complex consists of equimolar amounts of two small polypeptides. The two polypeptides have very similar molecular weights and amino acid composition but are clearly separable by eithr SDS polyacrylamide gradient gel electrophoresis or isoelectric focussing.
