Fig. 9. Orientation of a suggested Tyr190-Lys38 cation- interaction. The two side chains are taken from one of the 20 ensemble Bgtx· 18-mer structures depicted in Fig. 5. a, the distance between the NZ of Lys38 and the CE2 of Tyr190 is 5.49 Å; b, the distance between the NZ of Lys38 and the CE1 of Tyr190 is 5.85 Å; c, the distance between the CG of Tyr190 and the NZ of Lys38 is 5.53 Å.
