'''''We evaluate the repertoire of winged helix-turn-helix domains (wHTHs), a class of DNA-binding TFs in bacterial sequence genomes. The repertoire of wHTHs in terms of their partner domains, or PaDos was evaluated. Based on the PaDos, we defined three main groups of families: i) monolithic, those families with little diversity of PaDos, such as LysR; ii) promiscuous, those families with a high diversity of PaDos; iii) monodomain, with families of small sizes, such as MarR. These findings suggest that PaDos have a very important role in the diversification of regulatory responses in bacteria, probably contributing to their regulatory complexity.'''''
