RL Biochemistry 40:9799-9809(2001).
CC -!- FUNCTION: Catalyzes the oxidation of primary alcohols including
CC methanol.
CC -!- CATALYTIC ACTIVITY: A primary alcohol + 2 cytochrome c(L) = an
CC aldehyde + 2 reduced cytochrome c(L) + 2 H(+).
CC -!- COFACTOR: Binds 1 PQQ group per subunit. PQQ is inserted between
CC disulfide Cys-130-Cys-131 and the indole ring of Trp-270.
CC -!- COFACTOR: Binds 1 calcium ion per subunit.
CC -!- SUBUNIT: Heterotetramer composed of 2 alpha and 2 beta subunits.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Peripheral membrane
CC protein; Periplasmic side. Note=Periplasmic, but associated with
CC inner membrane.
CC -!- SIMILARITY: Belongs to the bacterial PQQ dehydrogenase family.
CC -!- SEQUENCE CAUTION:
CC Sequence=ACS42169.1; Type=Erroneous initiation;
