Binds 1 PQQ group per subunit. PQQ is inserted between disulfide Cys-130-Cys-131 and the indole ring of Trp-270.

Binds 1 calcium ion per subunit.

Subunit structure

Heterotetramer composed 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.
