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:0000256|HAMAP-Rule:MF_02226}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-allulose 6-phosphate = keto-D-fructose 6-phosphate;
CC Xref=Rhea:RHEA:28426, ChEBI:CHEBI:57579, ChEBI:CHEBI:61519;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02226};
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02226};
CC -!- PATHWAY: Carbohydrate degradation; D-allose degradation.
CC {ECO:0000256|HAMAP-Rule:MF_02226}.
CC -!- SIMILARITY: Belongs to the ribulose-phosphate 3-epimerase family. AlsE
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_02226}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
