CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01605};
CC   -!- PATHWAY: Carbohydrate degradation; pentose phosphate pathway; D-
CC       ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage): step
CC       2/3. {ECO:0000255|HAMAP-Rule:MF_01605}.
CC   -!- SIMILARITY: Belongs to the cycloisomerase 2 family. {ECO:0000255|HAMAP-
