CC         EC=5.3.1.6; Evidence={ECO:0000255|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:0000255|HAMAP-Rule:MF_00170}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00170}.
CC   -!- SIMILARITY: Belongs to the ribose 5-phosphate isomerase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00170}.
