Structure of A206W. (A) Electron density for Trp206 (polder omit, 4σ). (B) Overlay of A206W onto the tunnel system of the open conformation of the wild-type GsPutA, emphasizing how Trp206 blocks tunnel 2a. (C) Comparison of A206W (sand) with the open conformation of wild-type GsPutA (gray, PDB ID 4NM9).
