Procedure

The degradation H-Tyr-Gly-Gly-Phe-Leu-OH (SEQ ID NO: 12) (˜1.8×10−4 M) in 50 MM phosphate buffer solutions of pH 7.4 containing carboxypeptidase A (1 U/ml) was studied as described above. The pseudo first-order rate constant for the degradation was estimated to 9.8×10−1 min−1 and the corresponding half-life calculated to 0.7 min as previously described.
