ID 1.1.1.95 DE phosphoglycerate dehydrogenase. AN 3-phosphoglycerate dehydrogenase. AN 3-phosphoglyceric acid dehydrogenase. AN 3PHP reductase. AN alphaKG reductase. AN alpha-phosphoglycerate dehydrogenase. AN D-3-phosphoglycerate dehydrogenase. AN glycerate-1,3-phosphate dehydrogenase. AN glycerate 3-phosphate dehydrogenase. AN PGDH. AN phosphoglycerate oxidoreductase. AN phosphoglyceric acid dehydrogenase. CA (2R)-3-phosphoglycerate + NAD(+) = 3-phosphooxypyruvate + H(+) + NADH. CC -!- Catalyzes the first committed and rate-limiting step in the CC phosphoserine pathway of serine biosynthesis. CC -!- The reaction occurs predominantly in the direction of reduction. CC -!- The enzyme from the bacterium Escherichia coli also catalyzes the CC activity of EC 1.1.1.399.
