CC   -!- FUNCTION: Part of the heterotrimer that catalyzes the conversion of D-
CC       gluconate to 2-dehydro-D-gluconate. The role of this subunit in the
CC       heterotrimer is not known.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=A + D-gluconate = 2-dehydro-D-gluconate + AH2;
CC         Xref=Rhea:RHEA:12769, ChEBI:CHEBI:13193, ChEBI:CHEBI:16808,
CC         ChEBI:CHEBI:17499, ChEBI:CHEBI:18391; EC=1.1.99.3;
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   -!- PTM: Predicted to be exported by the Tat system. The position of the
CC       signal peptide cleavage has been experimentally proven.
