Molecular function

3-PGK, 3-phosphoglycerate kinase activity, 3-phosphoglycerate phosphokinase activity, 3-phosphoglyceric acid kinase activity, 3-phosphoglyceric acid phosphokinase activity, 3-phosphoglyceric kinase activity, ATP-3-phospho-D-glycerate-1-phosphotransferase activity, ATP:3-phospho-D-glycerate 1-phosphotransferase activity, ATP:D-3-phosphoglycerate 1-phosphotransferase activity, PGK, glycerate 3-phosphate kinase activity, glycerophosphate kinase activity, phosphoglyceric acid kinase activity, phosphoglyceric kinase activity, phosphoglycerokinase activity

Catalysis of the reaction: 3-phospho-D-glycerate + ATP = 3-phospho-D-glyceroyl phosphate + ADP + H+.
