CC -!- FUNCTION: Probably catalyzes the hydrolysis of L-ascorbate-6-P into 3-
CC keto-L-gulonate-6-P. Is essential for L-ascorbate utilization under
CC anaerobic conditions. {ECO:0000255|HAMAP-Rule:MF_01266}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + L-ascorbate 6-phosphate = 3-dehydro-L-gulonate 6-
CC phosphate; Xref=Rhea:RHEA:28803, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:58774, ChEBI:CHEBI:61698; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01266};
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01266};
CC -!- PATHWAY: Cofactor degradation; L-ascorbate degradation; D-xylulose 5-
CC phosphate from L-ascorbate: step 1/4. {ECO:0000255|HAMAP-
CC Rule:MF_01266}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01266}.
CC -!- INDUCTION: Induced by L-ascorbate. Repressed by UlaR.
CC {ECO:0000255|HAMAP-Rule:MF_01266}.
CC -!- SIMILARITY: Belongs to the UlaG family. {ECO:0000255|HAMAP-
CC Rule:MF_01266}.
CC -!- SEQUENCE CAUTION:
CC Sequence=ABB68685.1; Type=Erroneous initiation; Evidence={ECO:0000305};
