IntEnz Enzyme Nomenclature


Accepted name:
glycerate 2-kinase
Other names:
glycerate kinase (2-phosphoglycerate forming)
Systematic name:
ATP:D-glycerate 2-phosphotransferase




A key enzyme in the nonphosphorylative Entner-Doudoroff pathway in archaea [1,2]. In Hyphomicrobium methylovorum GM2 the enzyme is involved in formaldehyde assaimilation 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].
