The Complete Amino Acid Sequence of Human P2 Protein

Abstract
The complete amino acid sequence of P2 protein from human peripheral nerve myelin was determined from nine staphylococcal protease peptides and four cyanogen bromide peptides. Human P2 protein is composed of 131 amino acids and has a molecular weight of 14,818. Compared to bovine P2 protein, there are replacements at nine positions (human↔bovine): 18(Asp↔Glu), 39(Thr↔Arg), 56(Thr↔Pro), 83(Ile↔Thr), 87(Gln↔Ala), 96(Arg↔Lys), 100(Lys↔Asn), 115 (Ala↔Val), and 121(Gly↔Asp).
