Amino acid sequence of cyanogen bromide fragment CB3 of hog pepsin

Abstract

On the basis of the knowlidge of thermolytic, chymotryptic and substilisin peptides the amino acid sequence was determined of cyanogen bromide fragment CB3 representing the region between methionine residues I and II of pepsin: Thr-Gly-Ile-Leu-Gly-Tyr-Asp-Thr-Val-Gln-Val-Gly-Gly-Ile-Ser-Asp-Thr-Asn-Gln-Ile-Phe-Gly-Leu-Ser-Glu-Thr-Glu-Pro-Gly-Ser-Phe-Leu-Tyr-Tyr-Ala-Pro-Phe-Asp-Gly-Ile-Leu-Gly-Leu-Ala-Tyr-Pro-Ser-Ile-Ser-Ala-Ser-Gly-Ala-Thr-Pro-Val-Phe-Asp-Asn-Leu-Trp-Asp-Gln-Gly-Leu-Val-Ser-Gln-Asp-Leu-Phe-Ser-Val-Tyr-Leu-Ser-Ser-Asn-Asp-Asp-Ser-Gly-Ser-Val-Val-Leu-Leu-Gly-Gly-Ile-Asp-Ser-Ser-Tyr-Tyr-Thr-Gly-Ser-Leu-Asn-Trp-Val-Pro-Val-Ser-Val-Glu-Gly-Tyr-Trp-Gln-Ile-Thr-Leu-Asp-Ser-Ile-Thr-Met.
