ENZYME entry: EC

Accepted Name
Alcohol dehydrogenase (nicotinoprotein).
Alternative Name(s)
NDMA-dependent alcohol dehydrogenase.
Nicotinoprotein alcohol dehydrogenase.
Reaction catalysed
Ethanol + acceptor <=> acetaldehyde + reduced acceptor
  • 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) can serve this function in vitro.
  • The enzyme from the Gram-positive bacterium Amycolatopsis methanolica can accept many primary alcohols as substrates, including benzylalcohol.
