Function
function
Catalyzes the isomerization of L-ribulose 5-phosphate to D-xylulose 5-phosphate. Is involved in the anaerobic L-ascorbate utilization.
Catalytic activity
- L-ribulose 5-phosphate = D-xylulose 5-phosphate
Cofactor
Note: Binds 1 zinc ion per subunit.
Pathway
Cofactor degradation; L-ascorbate degradation; D-xylulose 5-phosphate from L-ascorbate: step 4/4.
