DE   serine racemase.
CA   L-serine = D-serine.
CC   -!- Highly selective for L-serine as substrate.
CC   -!- D-Serine is found in type-II astrocytes in mammalian brain, where it
CC       appears to be an endogenous ligand of the glycine site of N-methyl-D-
CC       aspartate (NMDA) receptors.
CC   -!- The reaction can also occur in the reverse direction but does so more
CC       slowly at physiological serine concentrations.
