Penicillin amidase catalyses the synthesis of amide bond in very high
yield (>98%), using equimolar concentrations of the amine and the phen
ylacetic components. In situ hydrated phosphates were employed for con
trolling the water activity in a benzene/water system (97:3 v/v), wher
e the water is taken up by the salt with formation of the hydrated spe
cies. Copyright (C) 1996 Elsevier Science Ltd
