Figure 5.
Stereoviews of the 20 lowest-energy structures calculated for the NC:U5GGU complex. (a) Best-fit superposition of the backbone atoms of the N-terminal zinc knuckle. The figure displays the backbone atoms of residues Val 13-Cys 49 (black), heavy atoms of the N-terminal zinc knuckle (Cys and His in yellow and blue, respectively), and RNA residues U107 (orange), G106 and G108 (green). The backbone atoms of residues that link the two zinc knuckles are shown in red. (b) Same as in (a), except that the backbone atoms of the C-terminal zinc knuckle are superposed.
