Total enzymatic synthesis of cholecystokinin CCK-5.[Pubmed:15309578]
Amino Acids. 2004 Aug;27(1):101-5.
This paper describes the enzymatic synthesis of the C-terminal fragment H-Gly-Trp-Met-Asp-Phe-NH2 of cholecystokinin. Immobilized enzymes were used for the formation of all peptide bonds except thermolysin. Beginning the synthesis with phenylacetyl (PhAc) glycine carboxamidomethyl ester (OCam) and H-Trp-OMe by using immobilized papain as biocatalyst in buffered ethyl acetate, the dipeptide methyl ester was then coupled directly with Met-OEt.HCl by alpha-chymotrypsin/Celite 545 in a solvent free system. For the 3+2 coupling PhAc-Gly-Trp-Met-OEt had to be converted into its OCam ester. The other fragment H-Asp(OMe)-Phe-NH2 resulted from the coupling of Cbo-Asp(OMe)-OH with H-Phe-NH2.HCl and thermolysin as catalyst, followed by catalytic hydrogenation. Finally PhAc-Gly-Trp-Met-Asp-Phe-NH2 was obtained in a smooth reaction from PhAc-Gly-Trp-Met-OCam and H-Asp(OMe)-Phe-NH2 with alpha-chymotrypsin/Celite 545 in acetonitrile, followed by basic hydrolysis of the beta-methyl ester. The PhAc-group is removed with penicillin G amidase and CCK-5 is obtained in an overall isolated yield of 19.6%.
Enzymatic synthesis of a CCK-4 tripeptide fragment.[Pubmed:12697455]
Di Yi Jun Yi Da Xue Xue Bao. 2003 Apr;23(4):289-92.
OBJECTIVE: To synthesize a tripeptide derivative Phac-Met-Asp(OMe)-Phe -NH2, which is a fragment of the gastrin C-terminal tetrapeptide CCK-4, by enzymatic reaction. METHODS: Three free enzymes, alpha-chymotrypsin, papain and thermolysin from acyl donor Phac-Met-OCam was involved in three steps. The choice of appropriate enzymes and solvents was selected. RESULTS: All enzymatic reactions were obtained in reasonable yields(63%-92%). FAB-MS and FD-MS verified the correct molecular mass of the peptides. CONCLUSION: Studies on the alpha-chymotrypsin catalyzed coupling reaction between Phac-Met-OCam and H-Asp(OMe)2 have focused on the low water content media. By papain catalyzed saponification of Phac-Met-Asp(OMe)2, alpha-methyl ester of aspartic acid is selectively hydrolyzed to retain beta-methyl ester, and Phac-Met-Asp(OMe)-OH and H-Phe-NH2 can be coupled efficiently by thermolysin.
