Chains	Enzyme Name	Description	Catalytic Residues
A	phosphoglycerate kinase M-CSA #40	The first energy-producing reaction of glycolysis is catalysed by phosphoglycerate kinase (PGK). This enzyme is unusual among kinases in that, biologically it functions mainly in the reverse (with respect to the EC) direction to phosphorylate ADP. Here we show the biological direction. This important energy saving feature makes it fairly ubiquitous. In all known cases it requires an Mg(II) ion to reduce charge repulsion between the negatively charged phosphate groups, enabling the two charged phosphate groups to interact.
