Full enzymatic synthesis of a fragment of osteogenic growth peptide (OGP), a precursor of bioactive pentapeptide OGP(10-14) (Z-TyrGlyPheGlyGlyOEt), was accomplished by papain, α-chymotrypsin, and thermolysin via 2+3 or 3+2 synthetic routes in organicsolvents for the first time. The factors influencing the enzymatic synthesis of fragments of OGP(10-14) were systematically studied.

Full enzymatic synthesis of a precursor of osteogenic growth peptide fragment (10-14), Z-Tyr-Gly-Phe-Gly-Gly--OEt, was accomplished using immobilized proteases on molecular sieve MCM-22 by adsorption as catalyst via 3+2 synthetic route for the first time. The reuse time of immobilized enzyme was dependent on concrete reaction system. Compared with free enzyme, the reaction rate catalyzed by immobilized
