EC 3.1.4.61

Accepted name: cyclic 2,3-diphosphoglycerate hydrolase

Reaction: cyclic 2,3-bisphosphoglycerate + H2O = 2,3-diphosphoglycerate

Systematic name: cyclic 2,3-diphosphoglycerate phosphohydrolyase

Comments: The enzyme degrades cyclic 2,3-bisphosphoglycerate, a thermoprotectant that is produced by certain archaeal genera. Two different enzymes that catalyse this activity, one soluble and one membrane-bound, have been characterized from the archaeon Methanothermobacter thermautotrophicus.
