Mechanistic details of PW4. (A) The hydrogen bond distances between the NH2 atom of R8 and the O6 atom of G64 (red trace) and between the NH2 atom of R8 and the O6 atom of G70 (blue trace) and the salt bridge between the NH1 atom of R8 and the O1P atom of U72 (green trace). (B) The hydrogen bond distance between the NH1 atom of R14 and the O6 atom of G70 (red trace) and the salt bridges between the NH1 atom of R14 and the O1P atom of C69 (blue trace) and between the NH2 atom of R14 and the O2P atom of A68 (green trace). (C) The hydrogen bond distances between NH1 atom of R15 and the N7 atom of A73 (red trace) and between the NH2 atom of R15 and the O2 atom of U72 (blue trace) and the salt bridge between the NH2 atom of R15 and the O1P atom of C44 (green trace). The scale on y axis is limited to 20 Å because the presented interactions form at distances below 3.5 Å. The data corresponding to all distance values on the y axis are shown in Fig. S9D; cf. Fig. 3 for all other details. To see this figure in color, go online.
