Laccase-Catalyzed Oxidation of Mn in the Presence of Natural Mn Chelators as a Novel Source of Extracellular H2O2 Production and Its Impact on Manganese Peroxidase

Abstract

A purified and electrophoretically homogeneous blue laccase from the litter-decaying basidiomycete Stropharia rugosoannulata with a molecular mass of approximately 66 kDa oxidized Mn to Mn , as assessed in the presence of the Mn chelators oxalate, malonate, and pyrophosphate. At rate-saturating concentrations (100 mM) of these chelators and at pH 5.0, Mn… (More)
