show Brenda entry
EC number
1.1.5.5
Accepted name
alcohol dehydrogenase (quinone)
Reaction
ethanol + ubiquinone = acetaldehyde + ubiquinol
Other name(s)
type III ADH, membrane associated quinohaemoprotein alcohol dehydrogenase
Systematic name
alcohol:quinone oxidoreductase
Comment
Only described in acetic acid bacteria where it is involved in acetic acid production. Associated with membrane. Electron acceptor is membrane ubiquinone. A model structure suggests that, like all other quinoprotein alcohol dehydrogenases, the catalytic subunit 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; the catalytic subunit also has a heme c in the C-terminal domain. The enzyme has two additional subunits, one of which contains three molecules of heme c. It does not require amines for activation. It has a restricted substrate specificity, oxidizing a few primary alcohols (C2 to C6), but not methanol, secondary alcohols and some aldehydes. It is assayed with phenazine methosulfate or with ferricyanide.
