==Structure of Microsomal Glutathione Transferase 1 in Complex with Glutathione==
-
Synthesis of mediators of fever, pain and inflammation as well as, protection against reactive molecules and oxidative stress is a hallmark, of the MAPEG superfamily (membrane associated proteins in eicosanoid and, glutathione metabolism). The structure of a MAPEG member, rat microsomal, glutathione transferase 1, at 3.2 A resolution, solved here in complex, with glutathione by electron crystallography, defines the active site, location and a cytosolic domain involved in enzyme activation. The, glutathione binding site is found to be different from that of the, canonical soluble glutathione transferases. The architecture of the, homotrimer supports a catalytic mechanism involving subunit interactions, and reveals both cytosolic and membraneous substrate entry sites, providing a rationale for the membrane location of the enzyme.
