Secondary Information

Protein Function catalyzes the first step in the pathway by converting D-3- phosphoglycerate (PGA), an intermediate in glycolysis, to phosphohydroxypyruvate (PHP) concomitant with the reduction of NAD+.  PGDH is required for tumor cell proliferation, but extracellular l-serine is not able to support cell proliferation. 
Biochemical Properties catalytic activity is regulated by feedback inhibition by L-serine; human enzyme appears to contain bound cofactor when isolated and the binding order appears to be coenzyme before substrate; slowly convert αKG to αHG. Three types of PGDH can be distinguished based on their domain structure. Type III PGDHs contain only a nucleotide binding and substrate binding domain. Type II PGDHs contain an additional regulatory domain (ACT domain), and Type I PGDHs contain a fourth domain, termed the ASB domain. There is no consistent pattern of domain content that correlates with organism type, and even when additional domains are present, they are not always functional.
