Figure 4. Contacts among residues of the YDR element in adjacent
tails. Detail of the CP channel in the closed state, showing
that the carboxylate group of Asp 9 in 3
forms a salt bridge with the guanidinium group of Arg 10 in 4,
and a hydrogen bond with the hydroxyl group of Tyr 8 in 4.
The carboxylate group of Asp 9 also forms hydrogen bonds with
the 3
main chain, as shown.
