Phylogenetic trees calculated for sequences of GmrS and GmrD domains presented as a tanglegram. The associations were made either between domains from one double-domain protein or between single-domain proteins which may form a functional dimeric GmrSD system. Clades with SH-like support values below 80 % were collapsed. The dots indicate GmrS-GmrD pairs from the heterodimeric GmrSD system. The thick line shows the GmrSD system from M. mobile which is an example of possible horizontal gene transfer
