A human FAD-dependent diaphorase, DIA4, has been studied in 29 independent human-rodent hybrids and in 17 subclones. The results suggest that the locus DIA4 is on chromosome 16.

A diaphorase (DIA4), different from similar enzymes so far described in man, has been detected electrophoretically in human tissues and fibroblasts. The enzyme which is active both with NADH and NADPH was missing in erythrocytes. It was consistently undetectable in part of the diploid fibroblast cultures analyzed. The activity could be separated by Cellogel electrophoresis from rodent diaphorases. In manmouse somatic cell hybrids human DIA4 segregated with chromosome 16. This result indicates that its structural gene is located on this autosome. The enzyme exhibits similarities with a NAD(P)H dehydrogenase (EC 1.6.99.2) described in rat liver.

A newly discovered human diaphorase, designated diaphorase-4, which accounts for a major part of the diaphorase activity of most tissues but does not occur in erythrocytes, is described. In contrast with other human diaphorases, it is dependent on FAD for activity after electrophoresis, inhibited by low concentrations of dicoumarol and shows a marked affinity for Cibacron Blue. The molecular weight was estimated to be 49000 +/- 1800 by gel filtration. Diaphorase-4 appears to show person-to-person quantitative variation, so that about 4% of the population lack appreciable enzyme activity, but it is not yet clear whether this variation is of genetic or non-genetic origin.
