Crystal structures of MjTX-II/rosmarinic acid (RA) and MjTX-II/ acetylsalicylic acid (ASA) complexes. (a) The overall structure of the MjTX-II/RA complex is shown as a cartoon representation. The RA (yellow) molecule is illustrated as stick representation. (b) Omit electron density map (coefficients 2|Fobs| - |Fcalc|) corresponding to RA is contoured at 1.0σ. (c) The overall structure of the MjTX-II/ASA complex is shown as a cartoon representation. ASA (yellow) molecules are illustrated as stick representation. (d) Omit electron density map (coefficients 2|Fobs| - |Fcalc|) corresponding to the ASA molecules bound to monomer A and B, respectively, are contoured at 1.0σ.
