    D-Serine is a co-agonist of the N-methyl-D-aspartate subtype of glutamate receptors, a major neurotransmitter receptor family in mammalian nervous systems. D-Serine is converted from L-serine, 90% of which is the product of the enzyme phosphoserine phosphatase (PSP). PSP from M. jannaschii (MJ) shares significant sequence homology with human PSP. PSPs and P-type ATPases are members of the haloacid dehalogenase (HAD)-like hydrolase family, and all members share three conserved sequence motifs. PSP and P-type ATPases utilize a common mechanism that involves Mg(2+)-dependent phosphorylation and autodephosphorylation at an aspartyl side chain in the active site. The strong resemblance in sequence and mechanism implies structural similarity among these enzymes.
