IUBMB Enzyme Nomenclature


Accepted name: glycerate 2-kinase

Reaction: ATP + D-glycerate = ADP + 2-phospho-(R)-glycerate

Other name(s): D-glycerate-2-kinase; glycerate kinase (2-phosphoglycerate forming); ATP:(R)-glycerate 2-phosphotransferase

Systematic name: ATP:D-glycerate 2-phosphotransferase

Comments: A key enzyme in the nonphosphorylative Entner-Doudoroff pathway in archaea [1,2]. In Hyphomicrobium methylovorum GM2 the enzyme is involved in formaldehyde assimilation I (serine pathway) [5]. In Escherichia coli the enzyme is involved in D-glucarate/D-galactarate degradation [6]. The enzyme requires a divalent metal ion [1].
