Phosphoglycerate kinase (EC 126.96.36.199) (PGK)  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.
