CC -!- FUNCTION: Catalyzes the decarboxylation of 3-keto-L-gulonate-6-P into
CC L-xylulose-5-P. Is involved in the anaerobic L-ascorbate utilization.
CC {ECO:0000255|HAMAP-Rule:MF_01267}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-dehydro-L-gulonate 6-phosphate + H(+) = CO2 + L-xylulose 5-
CC phosphate; Xref=Rhea:RHEA:14353, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16526, ChEBI:CHEBI:57829, ChEBI:CHEBI:58774; EC=4.1.1.85;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01267};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01267};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01267};
CC -!- PATHWAY: Cofactor degradation; L-ascorbate degradation; D-xylulose 5-
CC phosphate from L-ascorbate: step 2/4. {ECO:0000255|HAMAP-
CC Rule:MF_01267}.
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01267}.
CC -!- INDUCTION: Induced by L-ascorbate. Repressed by UlaR.
CC {ECO:0000255|HAMAP-Rule:MF_01267}.
CC -!- SIMILARITY: Belongs to the HPS/KGPDC family. KGPDC subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01267}.
