Corrections to the amino acid sequence of bovine chymotrypsinogen A.

Reinvestigation of the amino acid sequence of bovine chymotrypsinogen A suggests that the amino acid sequence at the N-terminus of the B-chain (residues 16-19) is -Ile-Val-Asn-Gly- rather than -Ile-Val-Gly-Asp- and that Ser-215 should be deleted.
