EC 1.1.99.36     
Accepted name: alcohol dehydrogenase (nicotinoprotein)
Reaction: ethanol + acceptor = acetaldehyde + reduced acceptor
Other name(s): NDMA-dependent alcohol dehydrogenase; nicotinoprotein alcohol dehydrogenase; np-ADH; ethanol:N,N-dimethyl-4-nitrosoaniline oxidoreductase
Systematic name: ethanol:acceptor oxidoreductase
Comments: Contains Zn2+. Nicotinoprotein alcohol dehydrogenases are unique medium-chain dehydrogenases/reductases (MDR) alcohol dehydrogenases that have a tightly bound NAD+/NADH cofactor that does not dissociate during the catalytic process. Instead, the cofactor is regenerated by a second substrate or electron carrier. While the in vivo electron acceptor is not known, N,N-dimethyl-4-nitrosoaniline (NDMA), which is reduced to 4-(hydroxylamino)-N,N-dimethylaniline, can serve this function in vitro. The enzyme from the Gram-positive bacterium Amycolatopsis methanolica can accept many primary alcohols as substrates, including benzylalcohol [1].
