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}.
