Abstract
There is provided a process for enhancing the activity of a phenol oxidizing enzyme, comprising adding to the enzyme, as an enhancer for the activity of the enzyme, one or more compounds having the formula: ##STR1## wherein: PA1 A is an optionally substituted electron-withdrawing group, chosen from the group consisting of nitrile, carboxyl, and esters and salts thereof, amides, aldehydes, ketones, sulfoxides, sulfones, or sulphonates, and PA1 B is an optionally substituted electron-donating group, chosen from the group consisting of the oxide anion, sulfide anion, oxides, amines, imines, hydroxides, sulfides, ethers, carboxylic acids, and halogen substituents, and PA1 R.sub.1 -R.sub.5 may each independently represent hydrogen, hydroxy, halogen, nitroso, formyl, carboxyl, and esters and salts thereof, carbamoyl, sulfo, and esters and salts hereof, sulfamoyl, nitro, amino, phenyl, C.sub.1 -C.sub.20 alkyl, C.sub.1 -C.sub.8 alkoxy, carbonyl-C.sub.1 -C.sub.6 -alkoxy, aryl-C.sub.1 -C.sub.6 -alkyl, and R.sub.2 and R.sub.5 together may form an alkylene group or an alkenylene group.
