Definition of diaphorase in English:



  • An enzyme of the flavoprotein type, able to oxidize a reduced form of the coenzyme NAD.

    • ‘Active enzyme systems not consistently resolved for this species were: ACO, adenylate kinase, diaphorase, EST, G - 6 - PDH, GSR, IDH, and PGI.’
    • ‘Neither the antennal nerve nor the tracts that carry the axons of projection neurons show diaphorase activity.’
    • ‘We found that the morphology of the primary myenteric plexus meshwork, when stained with NADPH diaphorase and nNOS, was very similar in colon and appendix in the newborn period.’
    • ‘In one of these species, for the most numerous caudal cluster in the reticular formation, NADPH diaphorase labels a dorsal sub-group in Xenopus which is thought to correspond to a well-described GABAergic population, the mhr neurons.’
    • ‘The monomorphic loci were: isocitrate-dehydrogenase, diaphorase (E.C.1.6.99.-, loci Dia1 and Dia2), leucine aminopeptidase and peroxidase anodic.’


1930s: from Greek diaphoros different + -ase.
