CC   -!- FUNCTION: Catalyzes the isomerization of L-xylulose-5-phosphate to L-
CC       ribulose-5-phosphate. Is involved in the anaerobic L-ascorbate
CC       utilization. {ECO:0000255|HAMAP-Rule:MF_01951}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-ribulose 5-phosphate = L-xylulose 5-phosphate;
CC         Xref=Rhea:RHEA:18497, ChEBI:CHEBI:57829, ChEBI:CHEBI:58226;
CC         EC=5.1.3.22; Evidence={ECO:0000255|HAMAP-Rule:MF_01951};
CC   -!- PATHWAY: Cofactor degradation; L-ascorbate degradation; D-xylulose 5-
CC       phosphate from L-ascorbate: step 3/4. {ECO:0000255|HAMAP-
CC       Rule:MF_01951}.
CC   -!- INDUCTION: Induced by L-ascorbate. Repressed by UlaR.
CC       {ECO:0000255|HAMAP-Rule:MF_01951}.
CC   -!- SIMILARITY: Belongs to the L-ribulose-5-phosphate 3-epimerase family.
CC       {ECO:0000255|HAMAP-Rule:MF_01951}.
