Phylogenetic analysis of structural preconditions of autogenous control of gene expression of rplJL operon at the translation level in γ-proteobacteria

I. V. Krupskaya, E. B. Paton

Phylogenetic analysis of structural preconditions of autogenous control regulation of gene expression of rplJL operon at the translation level in γ-proteobacteria has been performed. The structural preconditions of both L10 ribosomal protein and its RNA targets, which determine the possibility and the specificity of L10-RNA interaction have been studied. Phylogenetic comparison provides evidence for similarity of structural preconditions of the feedback regulation mechanism in γ-proteobacteria and E.coli, except for the endosimbionts.
