... O4 and O5, instead of O5 and O6 (Fig. 3B). At the same time, Arg240 can make more favourable interactions with Gln172 and Asp248. O6 now appears to lack a fixed hydrogen-bonding part- ner. The interactions ... O5 and O6 in the +1 site is thus assumed by Arg251 in Tr_Cel 7A. The main- chain atoms of Arg251 are  3A ˚ away from those of Arg240, but the functional guanidino gro...
