Versuchsvorschrift
330 mg (1 mmole) of Z-L-Tyr-OMe, 400 mg (2.2 mmole) of H-Gly-Gly-Ome, HCl were suspended in 5 mL DMSO and 5 mL 0.1 M tris-HCl, pH 8.9. 25 mg of α-chymotrypsin were added and the reaction stirred for 30 minutes. Five volumes of ice water were added, and the precipitate collected by filtration. Yield 312 mg (70%, based on acyl-donor). Amino acid analysis: tyr1.0,gly2.1.
