General annotation (Comments)

Function	Catalyzes the isomerization of L-ribulose 5-phosphate to D-xylulose 5-phosphate. Is involved in the anaerobic L-ascorbate utilization By similarity.
Catalytic activity	L-ribulose 5-phosphate = D-xylulose 5-phosphate. HAMAP MF_01952
Cofactor	Binds 1 zinc ion per subunit Potential.
Pathway	Cofactor degradation; L-ascorbic acid degradation; D-xylulose 5-phosphate from L-ascorbic acid: step 4/4. HAMAP MF_01952
Induction	Induced by L-ascorbate. Repressed by ulaR By similarity.
Sequence similarities	Belongs to the aldolase class II family. AraD/fucA subfamily.
