Abstract
The amino acid sequence of component 0.62, a protein derived from wool keratin, with molecular weight of 6950, rich in glycine and aromatic residues, has been determined. The protein contains no lysine, histidine, glutamic acid, isoleucine or methionine. Of the total residues, more than 50% are glycine and aromatic amino acids. The sequence contains two sections rich in glycine, (Gly‐X)3 and (Gly‐X)4, which comprise 22% of the sequence.
