Fig. 3: mL116 binding to rRNA motif in fragments LSU-2, LSU-3, and LSU-5.

Fig. 3

a mL116 trimer is found in the central protuberance (CP). Each copy binds a 3′ terminus of rRNA fragment (LSU-2, LSU-3, LSU-5) in its central groove. b Each one of the three mL116 monomers in the central protuberance of the LSU binds a 3′ terminus of rRNA via the motif GXXAAA. A specific guanine binding site followed by three adenine bases stacked between arginine and phenylalanine. Insets showing contact distances and specific guanine binding as well as alternative stacking view.
