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=AAN83701.1; Type=Erroneous initiation; Evidence={ECO:0000305};
