Inhibition of nitroblue tetrazolium reduction by metallothionein

Physiol Chem Phys. 1982;14(6):533-7.

Abstract

Metallothionein inhibited in a concentration-dependent fashion the reduction of nitroblue tetrazolium [NBT] mediated by xanthine oxidase and by NADH-phenazine methosulfate. This catalytic activity of metallothionein for dismutation of O2- is dependent on the copper content in metallothionein.
