A carboxylesterase with ab-lactamase fold from Arthrobacterpossesses a low level of hydrolytic activity (0.023 lmolÆmin )1 Æmg )1 ) when acting on a 6-aminohexanoate linear dimer byproduct of the nylon-6 industry (Ald). G181D⁄H266N⁄D370Y triple mutations in the parental esterase increased the Ald-hydrolytic activity 160-fold.

Catalytic oxidation of organic compounds is an extremely important field of chemistry, spanning the range from biological oxidations to large scale industrial production of commodity chemicals. However, many of these transformations can hardly be classified as organometallic reactions, since the catalysts (often simple metal salts) and the intermediates can be rather regarded as coordination complexes than organometallic compounds.
