CC -!- FUNCTION: Catalyzes the isomerization of L-ribulose 5-phosphate to D-
CC xylulose 5-phosphate. Is involved in the anaerobic L-ascorbate
CC utilization. {ECO:0000255|HAMAP-Rule:MF_01952}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-ribulose 5-phosphate = D-xylulose 5-phosphate;
CC Xref=Rhea:RHEA:22368, ChEBI:CHEBI:57737, ChEBI:CHEBI:58226;
CC EC=5.1.3.4; Evidence={ECO:0000255|HAMAP-Rule:MF_01952};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01952};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01952};
CC -!- PATHWAY: Cofactor degradation; L-ascorbate degradation; D-xylulose 5-
CC phosphate from L-ascorbate: step 4/4. {ECO:0000255|HAMAP-
CC Rule:MF_01952}.
CC -!- INDUCTION: Induced by L-ascorbate. Repressed by UlaR.
CC {ECO:0000255|HAMAP-Rule:MF_01952}.
CC -!- SIMILARITY: Belongs to the aldolase class II family. AraD/FucA
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01952}.
CC -!- CAUTION: Could be the product of a pseudogene. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CP000036; Type=Erroneous termination; Note=Truncated C-terminus.; Evidence={ECO:0000305};
