Glycerate kinase


In enzymology, a glycerate kinase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are ATP and -glycerate, whereas its two products are ADP and either 3-phospho--glycerate or 2-phospho--glycerate.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:-glycerate 3-phosphotransferase. Other names in common use include glycerate kinase , D-glycerate 3-kinase, D-glycerate kinase, glycerate-3-kinase, GK, D-glyceric acid kinase, and ATP:D-glycerate 2-phosphotransferase. This enzyme participates in 3 metabolic pathways: serine/glycine/threonine metabolism, glycerolipid metabolism, and glyoxylate-dicarboxylate metabolism.
This enzyme had been thought to produce 3-phosphoglycerate, but some glycerate kinases produce 2-phosphoglycerate instead.
