Function

CPGS_METFV Catalyzes the formation of cyclic 2,3-diphosphoglycerate (cDPG) by formation of an intramolecular phosphoanhydride bond at the expense of ATP. It is also able to catalyze the hydrolysis of cDPG but with significant slower rates (8-10 times). May be involved in thermoadaptation.^{[1] [2]}
