CC   -!- FUNCTION: Part of the heterotrimer that catalyzes the conversion of D-
CC       gluconate to 2-dehydro-D-gluconate. This subunit functions as the
CC       dehydrogenase.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=A + D-gluconate = 2-dehydro-D-gluconate + AH2;

CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692;
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       pH dependence:
CC         Optimum pH is 5.0. {ECO:0000269|PubMed:9352901};
CC       Temperature dependence:
CC         Optimum temperature is 30 degrees Celsius.
CC         {ECO:0000269|PubMed:9352901};
CC   -!- SUBUNIT: Heterotrimer.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Peripheral membrane
CC       protein {ECO:0000305}; Periplasmic side {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the GMC oxidoreductase family. {ECO:0000305}.
