Hydrolysis of -endorphin (a peptide containing 31 amino acid residues) produces the following amino acids: tyr, gly (3), phe (2), met, thr (3), ser (2), lys (5), gln (2), pro, leu (2), val (2), asn (2), ala (2), ile, his, and glu. Treatment with carboxypeptidase liberates gln. Treatment with Edman’s reagent liberates PTH-tyr. Treatment with trypsin produces the following peptides: K G-Q N-A-I-V-K Y-G-G-F-M-T-S-E-K N-A-H-K- S-Q-T-P-L-V-T-L-F-K Treatment with chymotrypsin produces the following peptides: K-N-A-I-V-K-N-A-H-K-K-G-Q Y-G-G-F M-T-S-E-K-S-Q-T-P-L-V-T-L-F What is the primary sequence of -endorphin?
