Other name(s): PHGDH (gene name); D-3-phosphoglycerate:NAD+ oxidoreductase; α-phosphoglycerate dehydrogenase; 3-phosphoglycerate dehydrogenase; 3-phosphoglyceric acid dehydrogenase; D-3-phosphoglycerate dehydrogenase; glycerate 3-phosphate dehydrogenase; glycerate-1,3-phosphate dehydrogenase; phosphoglycerate oxidoreductase; phosphoglyceric acid dehydrogenase; SerA; 3-phosphoglycerate:NAD+ 2-oxidoreductase; SerA 3PG dehydrogenase; 3PHP reductase

Systematic name: 3-phospho-D-glycerate:NAD+ 2-oxidoreductase

Comments: This enzyme catalyses the first committed and rate-limiting step in the phosphoserine pathway of serine biosynthesis. The reaction occurs predominantly in the direction of reduction. The enzyme from the bacterium Escherichia coli also catalyses the activity of EC, 2-oxoglutarate reductase [6].
