Predicted interaction of the initial hit compound SID7975595 with flipped HID62 and HIP119 in receptor model 23. Generally, the actives do not have strong interactions with His62 or His119, yet varying histidine protonation states have a profound effect on the ranked results. Favorable interactions are observed with other binding site residues, such as Tyr132 and Tyr138 as depicted here
