Diaphorase (coenzyme factor)

DiAPHORASE (coenzyme factor), one of the enzymes capable of reoxidizing reduced cozymase, has been the subject of a number of papers coming from this Institute and from Cambridge, where it was discovered independently and approximately simultaneously [Adler et al. 1937; Dewan & Green, 1937]. It is found widely distributed in animal tissues [Green et al. 1937; Dewan, 1938; Euler & The results reported in this paper include an extension of the knowledge concerming the distribution of the enzyme in plant tissues, a further confirmation of its specificity as an oxidizing agent for coenzyme I, and a preliminary investigation of its action in respiratory systems other than those containing cytochrome carriers.
