phosphoglycerate dehydrogenase  M-CSA #785

3-phosphoglycerate dehydrogenase catalyses the oxidation of D-3-phosphoglycerate to 3-phosphohydroxypyruvate with concurrent reduction of NAD+ to NADH. This reaction is the first committed step in serine biosynthesis. In the following steps transamination of 3-phosphohydroxypyruvate with glutamate yields phosphoserine and the action of a phosphatase completes the biosynthesis. In prokaryotes and plants 3-phosphoglycerate dehydrogenase is inhibited by serine in an allosteric fashion.
