Comments [?]

Function Catalyzes the reversible epimerization of D-allulose 6-phosphate to D-fructose 6-phosphate. Can also catalyze with lower efficiency the reversible epimerization of D-ribulose 5-phosphate to D-xylulose 5-phosphate.
Catalytic activity RHEA:28426: D-allulose 6-phosphate = keto-D-fructose 6-phosphate
Cofactor a divalent metal cation
Pathway Carbohydrate degradation; D-allose degradation.
Similarity Belongs to the ribulose-phosphate 3-epimerase family. AlsE subfamily.

Keywords [?]
