The complete amino acid sequence of cytochrome c551 isolated from an aerobic photosynthetic bacterium, Erythrobacter sp. strain OCh 114, was determined. The cytochrome molecule was composed of a total of 119 amino acid residues and its molecular weight including heme was calculated to be 13,235. The sequence was (Sequence: see text). Its molecular weight indicates that this cytochrome is of the L-type. Sequence alignment with other bacterial cytochromes c shows that this cytochrome is similar to cytochromes c of Rhodobacter capsulatus, Rhodobacter sphaeroides, and Paracoccus denitrificans, which were grouped into the alpha-3 subcluster from the 16S rRNA sequence analysis.
