ENZYME entry: EC 1.1.9.1

Accepted Name
Alcohol dehydrogenase (azurin).
Alternative Name(s)
QHEDH.
Reaction catalysed
A primary alcohol + azurin <=> an aldehyde + reduced azurin
Cofactor(s)
Heme; Pyrroloquinoline quinone.
Comment(s)
  • Occurs in Comamonas and Pseudomonas.
  • Does not require an amine activator.
  • Oxidizes a wide range of primary and secondary alcohols, and also aldehydes and large substrates such as sterols; methanol is not a substrate.
  • Usually assayed with phenazine methosulfate or ferricyanide.
  • 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 1.1.98.1.
