Enzyme Information

1.1.1.37	Malate dehydrogenase. based on mapping to UniProt O43175 (S)-malate + NAD(+) = oxaloacetate + NADH. -!- Also oxidizes some other 2-hydroxydicarboxylic acids.
1.1.1.399	2-oxoglutarate reductase. based on mapping to UniProt O43175 (R)-2-hydroxyglutarate + NAD(+) = 2-oxoglutarate + NADH. -!- The enzyme catalyzes a reversible reaction. -!- The enzyme from the bacterium Peptoniphilus asaccharolyticus is specific for (R)-2-hydroxyglutarate. -!- The SerA enzyme from Escherichia coli can also accept (S)-2- hydroxyglutarate with a much higher Km, and also catalyzes the activity of EC 1.1.1.95.
1.1.1.95	Phosphoglycerate dehydrogenase. based on mapping to UniProt O43175 3-phospho-D-glycerate + NAD(+) = 3-phosphonooxypyruvate + NADH. -!- Catalyzes 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 catalyzes the activity of EC 1.1.1.399.
