DIHYDROTHIOCTYL DEHYDROGENASE—A FLAVOPROTEIN

Abstract
The [alpha]-ketoglutaric dehydrogenase complex has been separated into 2 fractions. One of them catalyzes the reduction of dyes by [alpha]-ketoglutarate. The other fraction which has thioctic reductase and diaphorase activities is a flavoprotein of high reducing potential (EO approximately[long dash]0.34 volt). Thioctic reductase is present also in spinach chloroplasts.
