Figure 5. Stabilizing Interactions at the Base of the Hinge Loop(A) Residue contacts within E6AP in the L shape conformation. Lys549 interacts with Asn822, Gln553 hydrogen bonds with Thr819, and Asp607 appears to interact with His609.(B) Residue contacts within WWP1/AIP5 in the shape conformation. Arg613 interacts with Gly610, and His621 hydrogen bonds with Asp675. Both pairs of interactions bridge the H3 helix to loop regions (S2/H3 and H4/H5 loops).(C) WWP1/AIP5 (residues 546–922) was used as a reference for wild-type autoubiquitylation activity.
