From: Phylogeny and structural modeling of the transcription factor CsqR (YihW) from Escherichia coli

Phylogenetic tree of CsqR and its homologs from Gamma-, Beta-, Alphaproteobacteria and Actinomycetes. The left panel shows the tree inferred using the maximum likelihood algorithm and rooted manually by the branch leading to CsqR homologs from Streptomyces venezuelae str. NRRL B-65442 and Ruania alkalisoli str. RN3S43. The right panel features the first 62 positions of the multiple sequence alignment. Methionines aligned to Met25 of the reference E. coli str. K-12 MG1655 are marked violet.
