O-(Hydroxyacetyl)-L-beta-phenyllactic acid that was conceived as a mechanism-based inactivator for carboxypeptidase A from the X-ray crystal structure of the enzyme complexed with slowly hydrolyzed substrate, Gly-Tyr and a proposed mechanism for the catalytic action, indeed, inactivated the enzyme with the inactivation potency (k(inact)/K-i) of 0.057 M(-1)s(-1).
