ENZYME entry: EC

Accepted Name
methanol dehydrogenase (cytochrome c)
Alternative Name(s)
methanol dehydrogenase
Reaction catalysed
a primary alcohol + 2 Fe(III)-[cytochrome cL] <=> an aldehyde + 2 Fe(II)-[cytochrome cL] + 2 H(+)
  • A periplasmic quinoprotein alcohol dehydrogenase that only occurs in methylotrophic bacteria.
  • It uses the novel specific cytochrome cL as acceptor.
  • Acts on a wide range of primary alcohols, including ethanol, duodecanol, chloroethanol, cinnamyl alcohol, and also formaldehyde.
  • Activity is stimulated by ammonia or methylamine.
  • It is usually assayed with phenazine methosulfate.
  • Like all other quinoprotein alcohol dehydrogenases it has an 8-bladed 'propeller' structure, a calcium ion bound to the PQQ in the active site and an unusual disulfide ring structure in close proximity to the PQQ.
  • It differs from EC, alcohol dehydrogenase (cytochrome c), in having a high affinity for methanol and in having a second essential small subunit (no known function).
  • Formerly EC
