- Abbreviation for nicotinamide adenine dinucleotide phosphate (reduced form).- N.-cytochrome c2 reductase an enzyme catalyzing the reduction of 2ferricytochrome c2 to 2ferrocytochrome c2 at the expense of N.. SYN: cytochrome c2 reductase.- N. dehydrogenase a flavoprotein oxidizing N. to NADP+. SYN: N. diaphorase, old yellow enzyme, Warburg old yellow enzyme.- N. dehydrogenase (quinone) a flavoprotein oxidizing NADH or N. to NAD+ or NADP+ with quinones ( e.g., menadione) as hydrogen acceptors. SYN: DT-diaphorase, menadione reductase, phylloquinone reductase, quinone reductase.- N.-ferrihemoprotein reductase (fer′i-he-mo-pro′ten, fer′e-) an enzyme catalyzing the reduction of 2 ferricytochrome by N. to 2 ferrocytochrome; the physiologic acceptor is probably cytochrome P-450; hence, it has a role in steroid hydroxylations.
