Abstract

Ascorbyl free radical reductase was purified from the white rot fungus, Pleurotus ostreatus. The enzyme contained FMN as a prosthetic group, which was reduced by NADH and reoxidized by ascorbyl free radical. Reduction of ascorbyl free radical by the enzyme was observed by EPR spectroscopy.(omitted)
