Figure 2. Figur 2. An example of the non-reciprocal interactions between molecles related by non-crystallographic dyad with a small screw component. The carbonyls of (a) Ser92 nd b) Tyr94 in molecule 1 form hydrogen bonds ys93 N'' in molecule 343). The side-chain f Lys93 molecule ) is free in the solvent (Table C). The broken ines show contours in the (2F,,--F,) density.
