General annotation (Comments)

Function

Catalyzes the oxidation of primary alcohols including methanol By similarity.

Catalytic activity

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

Cofactor

Binds 1 PQQ group per subunit. PQQ is inserted between disulfide Cys-135-Cys-136 and the indole ring of Trp-275. Ref.2

Binds 1 calcium ion per subunit. Ref.2

Subunit structure

Heterotetramer composed of 2 alpha and 2 beta subunits. Ref.2

Subcellular location

Periplasm.

Miscellaneous

MDH is the major protein in the cell during growth on methanol (in P.denitrificans MDH constitutes up to 15% of the total cell protein).

Sequence similarities

Belongs to the bacterial PQQ dehydrogenase family.
