Phosphoglycerate kinase signature


Phosphoglycerate kinase (EC (PGK) [1] catalyzes the second step in the second phase of glycolysis, the reversible conversion of 1,3-diphospho-glycerate to 3-phosphoglycerate with generation of one molecule of ATP. PGK is found in all living organisms and its sequence has been highly conserved throughout evolution. It is a two-domain protein; each domain is composed of six repeats of an α/β structural motif. As a signature pattern for PGK's, we selected a conserved region in the N-terminal region.
