The following decapeptide composition resulted from an amino acid analysis: Asn, Glu, Trp, 2 Thr, Met, Leu, Ala, His, Phe 1. Pepsin (cleaves on N-side of aromatics) yielded a tripeptide composition (Trp, Leu, Glu), a hexapeptide, and a free Thr. 2. Chymotrypsin (cleaves C-side of aromatics) treatment gave dipeptide composition (Thr, Trp), tripeptide composition (Glu, Phe, Leu), and a pentapeptide. The first amino of the pentapeptide has a secondary alcohol. 3. Elastase (cleaves C-side of Gly and Ala) resulted in...
