Copper(II) carboxypeptidase A catalyses the oxidation of ascorbic acid and this reaction is inhibited by α-benzylsuccinate, a known inhibitor of the thiolesterase action of the copper enzyme; the pH dependencies of kcat and kcat/Km are similar near pH 7 to those seen for the peptidase and esterase activities of native carboxypeptidase A.

The 1:1 complex between an osmate ester and bovine serum albumin was found to be effective as an enantioselective catalyst in the cis-hydroxylation of alkenes, affording diols in up to 68% e.e. and turnover of the catalyst with t-butyl hydroperoxide.
