CC -!- FUNCTION: Catalyzes the reversible epimerization of D-allulose 6-
CC phosphate to D-fructose 6-phosphate. Can also catalyze with lower
CC efficiency the reversible epimerization of D-ribulose 5-phosphate to D-
CC xylulose 5-phosphate. {ECO:0000255|HAMAP-Rule:MF_02226,
CC ECO:0000269|PubMed:18700786, ECO:0000269|PubMed:9401019}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-allulose 6-phosphate = keto-D-fructose 6-phosphate;

CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000269|PubMed:18700786};
CC Note=Binds 1 divalent metal cation per subunit. Activity is highest
CC with Co(2+) > Mn(2+) > Zn(2+). {ECO:0000269|PubMed:18700786};
CC -!- PATHWAY: Carbohydrate degradation; D-allose degradation.
CC {ECO:0000255|HAMAP-Rule:MF_02226, ECO:0000269|PubMed:18700786}.
CC -!- SUBUNIT: Homohexamer. Trimer of dimers. {ECO:0000269|PubMed:18700786}.
CC -!- SIMILARITY: Belongs to the ribulose-phosphate 3-epimerase family. AlsE
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_02226, ECO:0000305}.
