title: The amino acid sequence of S-antigen: N-terminus and uveitogenic peptides.
abstract: Bovine S-antigen purified in the presence of proteinase inhibitors contained a protein (30%) having an acetylated N-terminus (Ac-Met-Lys-Ala-Asn-Lys-Pro-Ala...) and a protein (70%) having an N-terminus unblocked but four residues less (Lys-Pro-Ala-Pro-Asn-His-Val-Ile-Phe...). Sequencing studies showed that uveitogenic peptides produced by chymotryptic digestion of S-antigen derived from the C-terminal half of the protein.
