Methane is a promising carbon source for biosynthesis of biotechnologically useful compounds using aerobic methanotrophic bacteria as biocatalysts. Despite more than a century-long history of discovering and studying of methanotrophic microorganisms, knowledge of the molecular mechanisms of gene expression regulation by transcription factors in these bacteria is very limited with only a few isolated cases being published. Therefore, the identification of potential transcription factors for methanotrophic organisms and their target genes is not only a foreground fundamental problem in the research field of methanotrophy, but it is also especially relevant for the active development of biotechnological application of methane-oxidizing microorganisms. In this study a comparative genomics approach together with the structural modeling techniques were applied to reveal the TFs in the 20ZR genome and predict their target regulatory genes.
