General annotation (Comments)

Function	Catalyzes the isomerization of L-xylulose-5-phosphate to L-ribulose-5-phosphate. Is involved in the anaerobic L-ascorbate utilization By similarity.
Catalytic activity	L-ribulose 5-phosphate = L-xylulose 5-phosphate. HAMAP MF_01951
Pathway	Cofactor degradation; L-ascorbic acid degradation; D-xylulose 5-phosphate from L-ascorbic acid: step 3/4. HAMAP MF_01951
Induction	Induced by L-ascorbate. Repressed by ulaR By similarity.
Sequence similarities	Belongs to the HUMPI family.
