Structure of the GAC (Y466W) tetramer, with glutamine bound to all four subunits.A, glutamine-binding sites in the GAC (Y466W) tetramer are shown. B, the electron density for glutamine and the side chains engaging in hydrogen bonding with the substrate, together with the catalytically active residues. The electron density shown was calculated with the 2FoFc map at the contour level of 0.7 rmsd, which had been crossverified with the overlapping green density of the FoFc map at the contour level of 2.0 rmsd. GAC, glutaminase C.
