these results are consistent with the hydroxyl group of ser-254 playing a critical role in the cleavage of the peptide bond between gly-253 and ser-254 of the prophosphatidylserine decarboxylase and support the mechanism proposed by snell and coworkers ( recsei and snell ( 1984 ) annul rev . biochem . 53 , 357-387 ) for the formation of the prosthetic group of pyruvate-dependent decarboxylases .
