Phylogenetic distribution of yaaW and htgA overlapped genes. Phylogenetic distribution, open reading frames of overlapped genes, and protein domain organization of coded protein sequences according to Pfam database. ORF structure: Open reading frame of yaaW sequences is shown using left oriented dark-gray arrows; genome-annotated htgA sequences using right oriented black arrows; predicted htgA genes in this study right oriented pale-gray arrows; non-coding open reading frames right-oriented hatched arrows. Pfam domains: Pale-gray boxes indicated [Pfam:UPF0174] Pfam domain present in yaaW protein products; dark-gray boxes indicates GTPase domain of unknown function [Pfam:MMR_HSR1]. In the yaaW gene coding for [UniProtKB:Q8FLC7] the predicted htgA gene is shorter due to a non-sense mutation. Complete names of proteins are given in Additional file 3.
