IntEnz Enzyme Nomenclature
EC 6.5.1.9

Names

Accepted name:
cyclic 2,3-diphosphoglycerate synthase
Systematic name:
(2R)-2,3-bisphosphoglycerate ligase (cyclizing)

Reaction

Comments:

The enzyme is present in a number of methanogenic archaeal genera that accumulate cyclic 2,3-bisphosphoglycerate as a thermoprotectant. Activity is stimulated by potassium ions.
