Comments [?]

Function Catalyzes the isomerization of L-ribulose 5-phosphate to D-xylulose 5-phosphate. Is involved in the anaerobic L-ascorbate utilization.
Catalytic activity RHEA:22368: L-ribulose 5-phosphate = D-xylulose 5-phosphate
EC 5.1.3.4
Cofactor Zn(2+)
Note: Binds 1 zinc ion per subunit.
Pathway Cofactor degradation; L-ascorbate degradation; D-xylulose 5-phosphate from L-ascorbate: step 4/4.
Induction Induced by L-ascorbate. Repressed by UlaR.
Similarity Belongs to the aldolase class II family. AraD/FucA subfamily.
