General annotation (Comments)

Function

Catalyzes the oxidation of primary alcohols including methanol.

Catalytic activity

A primary alcohol + 2 cytochrome c(L) = an aldehyde + 2 reduced cytochrome c(L) + 2 H+.

Cofactor

Binds 1 calcium ion per subunit.

Binds 1 PQQ per subunit. PQQ is inserted between disulfide Cys-105-Cys-106 and the indole ring of Trp-239.

Subunit structure

Heterotetramer of 2 alpha and 2 beta subunits.

Subcellular location

Cell inner membrane; Peripheral membrane protein; Periplasmic side. Note: Periplasmic, but associated with inner membrane.

Sequence similarities

Belongs to the bacterial PQQ dehydrogenase family.
