CRYSTAL STRUCTURE OF HEMATOPOIETIC PROSTAGLANDIN D SYNTHASE COMPLEX WITH GLUTATHIONE
Overview
Hematopoietic prostaglandin (PG) D synthase is the key enzyme for, production of the D and J series of prostanoids in the immune system and, mast cells. We isolated a cDNA for the rat enzyme, crystallized the, recombinant enzyme, and determined the three-dimensional structure of the, enzyme complexed with glutathione at 2.3 A resolution. The enzyme is the, first member of the sigma class glutathione S-transferase (GST) from, vertebrates and possesses a prominent cleft as the active site, which is, never seen among other members of the GST family. The unique 3-D, architecture of the cleft leads to the putative substrate binding mode and, its catalytic mechanism, responsible for the specific isomerization from, PGH2 to PGD2.
