<p>There is provided a process for enhancing the activity of a phenol oxidizing enzyme, comprising adding to the enzyme, as an enhanc r for the activity of said enzyme, one or more compounds having formula (I): wherein: Z is an electron withdrawing group selected from the group consisting of optionally substituted alkyl/(hetero)aryl- -sulfone, -sulfoxide, -sulfonate, -carbonyl, -oxalyl, -amidoxalyl, -hydrazidoxalyl, -carboxyl and esters and salts thereof, -amidyl, -hydrazidyl, nitrile; R = Hydrogen or C1-C4; R1 = Hydrogen, C1-C4 alkyl or aryl; and R2, R3 may each independently represent hydrogen, hydroxy, halogen, nitroso, formyl, carboxyl and esters and salts thereof, carbamoyl, sulfo and esters and salts thereof, sulfamoyl, nitro, amino, phenyl, C1-C20 alkyl, C1-C8 alkoxy, carbonyl-C1-C6-alkoxy, aryl-C1-C6-alkyl and R2 and R3 may together with the relevant choice of n being 1, 2, 3 or 4 form a (multi)arylene, heteroarylene, alkylene or alkenylene group. The process is especially useful for removing coloured stains from fabrics in a washing process.</p> |
