ENZYME entry: EC 1.1.99.37

Accepted Name
Methanol dehydrogenase (nicotinoprotein).
Alternative Name(s)
NDMA-dependent methanol dehydrogenase.
Nicotinoprotein methanol dehydrogenase.
Reaction catalysed
Methanol + acceptor <=> formaldehyde + reduced acceptor
Cofactor(s)
Mg(2+); Zn(2+).
Comment(s)
  • Nicotinoprotein methanol dehydrogenases have a tightly bound NADP+/NADPH 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 has been detected in several Gram-positive methylotrophic bacteria, including Amycolatopsis methanolica, Rhodococcus rhodochrous and Rhodococcus erythropolis.
  • These enzymes are decameric, and possess a 5-fold symmetry.
  • Some of the enzymes can also dismutate formaldehyde to methanol and formate.
