CC -!- FUNCTION: Catalyzes the reversible conversion of ribose-5-phosphate to
CC ribulose 5-phosphate. {ECO:0000256|HAMAP-Rule:MF_00170}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=aldehydo-D-ribose 5-phosphate = D-ribulose 5-phosphate;
CC Xref=Rhea:RHEA:14657, ChEBI:CHEBI:58121, ChEBI:CHEBI:58273;
CC EC=5.3.1.6; Evidence={ECO:0000256|HAMAP-Rule:MF_00170};
CC -!- PATHWAY: Carbohydrate degradation; pentose phosphate pathway; D-ribose
CC 5-phosphate from D-ribulose 5-phosphate (non-oxidative stage): step
CC 1/1. {ECO:0000256|HAMAP-Rule:MF_00170}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00170}.
CC -!- SIMILARITY: Belongs to the ribose 5-phosphate isomerase family.
CC {ECO:0000256|HAMAP-Rule:MF_00170}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:OGN63224.1}.
