Figure 3 Surface representation of the 20 Å deep funnel leading to the catalytic site. Blue, side-chain nitrogens of Arg and Lys residues; red, side-chain oxygens of Asp and Glu; green, side-chain carbons of Tyr and Phe residues. Yellow, Zn^2+ ions; inhibitors shown as stick models. (A) Complex with GPI-18431; (B) complex with phosphate. Note the difference in the shape of the pocket because of withdrawal of the 'glutarate sensor' (Y700) in the phosphate complex.
