Figure 3
The nonphysiological THM-binding site. (a) The 2Fo − Fc map contoured at 1.3σ (calculated after refinement of the entire THM molecule) in the region of the nonphysiological binding site clearly shows the tetrahedral density of the sulfonyl group. (b) LIGPLOT (Wallace et al., 1995  ) representation of THM at the same site. The number of each residue involved is given, together with the chain designation of the DraE subunit it originates from (D or F). An identical THM-binding site is also observed between copies B and C. |
