SYSTEMATIC NAME
IUBMB Comments
3-phospho-D-glycerate:NAD+ 2-oxidoreductase
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 1.1.1.399, 2-oxoglutarate reductase [6].

the enzyme catalyzes the first reaction of serine and glycine biosynthesis. SER3 and SER33 encode phosphoglycerate dehydrogenases. The requirement for the SER-dependent phosphoglycerate pathway is conditional since the glyoxylate route of serine/glycine biosynthesis is glucose repressed. Ser33p is likely to be the main isoenzyme of the phosphoglycerate pathway during growth on glucose

binding of the inhibitor to the apoenzyme displays positive cooperativity in the binding of the first two serine molecules and negative cooperativity in the binding of the last two serine molecules. At least two NADH-induced conformational forms of the enzyme bind the inhibitor in the physiological range. Successive binding of NADH to the enzyme results in an increase in the affinity for the first inhibitor ligand bound and a lessening of both the positive and negative cooperativity of inhibitor binding

L-serine
-
the enzyme contains an ACT regulatory domain which binds L-serine for feedback regulation, binding site lies around residues H344-N364
L-serine
-
physiological inhibitor, exerts its effect on at least two steps in the kinetic mechanism. There is a small but significant effect on the dissociation constant of NADH, increasing the Kd to 5 and 23 microM from 0.6 and 9 microM, respectively, for the two sets of sites in the enzyme. After the second substrate is added, serine reduces the amplitude of the signal without a significant effect on the observed rate constants for binding. The serine concentration that reduces the amplitude by 50% is equal to the K0.5 for serine inhibition. Serine binding eliminates a conformational change subsequent to substrate binding by formation of a dead-end quaternary complex consisting of enzyme, coenzyme, substrate, and effector. The rate data conform to a model in which serine can bind to two forms of the enzyme with different affinities

-
very high expression of Phgdh. It is shown that Phgdh is distributed highly in the renal papilla and inner layer of the outer zone and moderately in the cortex, whereas it is almost negative in the outer layer of the outer zone. This heterogeneous distribution is due to selective expression in distinct tubular segments, i.e., the Bowman's capsule, proximal tubule, and thin limbs of the Henle's loop
