Distribution of controller protein (C-protein) homologs in Mollicutes. Phylogenetic tree was built based on 16S rRNA sequences. All displayed species have at least one RM-system (see Additional file 1: Table S1 for more detail). Presence of C-protein and its predicted binding site is indicated by number in brackets, which corresponds to a motif sequence on the right. In the current work we focused on the most frequent motif 1 (distributed within mycoplasmas). It has also several deviations: shorter spacer between repeats and inverted repeats instead of direct, but with the same consensus. There is acholeplasma-specific motif 2. Motif 3 is shared by M. symbae and M. californicum, but is completely different from the rest. However it is similar to the motif of C-protein of AdhI RM-system
