The previously reported irreversible inhibition of thermolysin by (DL)-N-chloroacetyl-N-hydroxyleucine methyl ester, an active site directed inactivator, is found to be due to the D-enantiomer. Thus, while the D-enantiomer inactivated the enzyme, no inhibitory activity was found with the L-enantiomer. A possible explanation is presented for the reversed stereochemistry in the inactivation reaction compared with that of substrate.
