Partial amino acid sequences of several globin chains from the sockeye salmon, Oncorhynchus nerka.
1. Partial amino acid sequences for several sockeye salmon hemoglobin beta-chains have been determined and compared to several other fish beta-chain sequences. 2. A 90% homology exists between the sockeye cathodal (C1) beta-chain and the trout Hb I beta-chain for residues 1-19. 3. The sockeye salmon anodal (A1-3) beta-chain is virtually identical to the trout HB IV beta-chain for the first 55 amino acid residues. 4. The alpha-chains of the sockeye salmon appear to be acetylated at the N-terminal position and about 0.6% of the sockeye hemoglobin is glycosylated.
