The Primary structure of the presumable BChl d-binding polypeptide of chlorobium vibrioforme f. thiosulfatophilum

Abstract

In addition to the previous isolated and sequenced polypeptides from green photosynthetic sulfur bacteria, which are presum ably involved in binding BChl c and e, an analogous polypeptide has been purified from the BChl (f-containing bacterium Chlorobium vibrioforme f. thiosulfatophilum. The prim ary structure of this 6.15 kD a polypeptide was determined. It shows an extremely high homology (98.3%) to the corresponding polypeptide from Pelodictyon luteolum, indicative of an important functional role. © 1990, Walter de Gruyter. All rights reserved.
