Function

Function:
Catalyzes the synthesis of D-serine from L-serine. D-serine is a key coagonist with glutamate at NMDA receptors. Has dehydratase activity towards both L-serine and D-serine.
Catalytic Activity:
L-serine = D-serine.
Cofactor:
COFACTOR: Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
Kinetics:
BIOPHYSICOCHEMICAL PROPERTIES: Kinetic parameters: KM=6.5 mM for L-serine
Enzyme Regulation:
ENZYME REGULATION: Allosterically activated by magnesium, and possibly also other divalent metal cations. Allosterically activated by ATP, ADP or GTP. Competitively inhibited by malonate.
Active Site:
ACT_SITE 56 56 Proton acceptor.
