CC   -!- FUNCTION: Catalyzes the formation of cyclic 2,3-diphosphoglycerate
CC       (cDPG) by formation of an intramolecular phosphoanhydride bond at the
CC       expense of ATP. {ECO:0000255|HAMAP-Rule:MF_01908}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2R)-2,3-bisphosphoglycerate + ATP + H(+) = ADP + cyclic (2R)-
CC         2,3-bisphosphoglycerate + phosphate; Xref=Rhea:RHEA:42412,

CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01908}.
CC   -!- SIMILARITY: Belongs to the cyclic 2,3-diphosphoglycerate synthetase
CC       family. {ECO:0000255|HAMAP-Rule:MF_01908}.
