The third amino acid sequence of a high potential iron-sulfur protein, that of the non-sulfur purple photosynthetic bacterium Rhodopseudomonas gelatinosa, has been determined. It consists of a single polypeptide chain of 74 amino acid residues, which is slightly smaller than the high potential iron-sulfur proteins from the sulfur purple bacteria Chromatium vinosum (85 residues) and Thiocapsa pfennigii (81 residues). The sequence of the gelatinosa protein is similar to the C. vinosum and T. pfennigii proteins with 38% and 37% identically matching residues, although six gaps are proposed for the comparison (the C. vinosum and T. pfennigii proteins have 44% identically matching residues out of 73 positions compared with only one 4-residue gap). Only 17 redisues, including the 4 cystein residues essential for binding the four-iron-sulfur chromophore, are invariant in the three known sequences. A discussion of the role of conserved residues in maintenance of the three-dimensional structure and in electron transport is presented.
