ENZYME entry: EC

Accepted Name
alcohol dehydrogenase (cytochrome c)
Reaction catalysed
a primary alcohol + 2 Fe(III)-[cytochrome c] <=> an aldehyde + 2 Fe(II)-[cytochrome c] + 2 H(+)
  • A periplasmic PQQ-containing quinoprotein.
  • Occurs in Pseudomonas and Rhodopseudomonas.
  • The enzyme from Pseudomonas aeruginosa uses a specific inducible cytochrome c550 as electron acceptor.
  • Acts on a wide range of primary and secondary alcohols, but not methanol.
  • It has a homodimeric structure (contrasting with the heterotetrameric structure of EC, methanol dehydrogenase (cytochrome c)).
  • It is routinely assayed with phenazine methosulfate as electron acceptor.
  • Activity is stimulated by ammonia or amines.
  • 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.
  • Formerly EC
