The grids were glow-discharged for 25 s at 25 mA with the chamber pressure set at 0.3 mbar (PELCO easiGlow; Ted Pella). The grids were prepared using the Leica GP2 plunge freezer with its chamber set to 10oC and 95% humidity. Samples of purified HIV-1 RT were diluted to 1mg/mL and 2 molar equivalents of the appropriate compound 12126065 were incubated on a 4oC rotator overnight to combine. A total of 4uL of HIV-1 RT and compound were applied to the backside of the Quantifoil grid and blotted for 4 seconds on the carbon side before plunge frozen in ethane at -181oC.. </details>
