ENZYME entry: EC 1.1.9.1

Accepted Name
alcohol dehydrogenase (azurin)
Alternative Name(s)
QHEDH
Reaction catalysed
a primary alcohol + 2 oxidized [azurin] <=> an aldehyde + 2 H(+) + 2 reduced [azurin]
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.
