From: Discovery of 20 novel ribosomal leader candidates in bacteria and archaea
Proposed rRNA imitation by r-leaders. Upper row: novel r-leader motifs. Lower row: rRNA binding site for the relevant r-protein. Annotations: as in Fig. 2. Yellow shading: nucleotides that interact with the relevant r-protein. Purple outline with yellow shading: interacting nucleotides that are similar in r-leader and rRNA. Purple outline: similar r-leader nucleotides that do not resemble the rRNA. H20-H40: Thermus thermophilus helix numbers from [39] or [40]. a L20 motif. b Archaeal motif for the eL15 protein. The asterisk marks a region of the bulged-G module that is only partially similar in the r-leader (see text). c S15 motifs in Halobacteria and Methanomicrobia. d S4 motif from Fusobacteriales
