The evolution of proline synthesis transcriptional regulation in gammaproteobacteria
2010
Moscow University Biological Sciences Bulletin
We report a conserved motif in the upstream region of the proA and proB genes, which are widely found among γ proteobacteria, particularly in the genera Pseudomonas, Marinobacter, and Shewanella. The conserved protein-DNA binding sites are 8 bp long. Some genes have double sites for cooperative factor binding. The phylogenetic profiles of binding sites and all protein factors were compared. We identify the tetR family protein, an ortholog of the NP_249058 protein from P. aeruginosa PAO1, as a

... anscription factor. Our algorithm was applied to construct the species tree with predicted regulation of the pro genes. The phylogeny of pro genes, transcription factor phylogeny, and a phylogeny of their binding sites were mapped onto the spe cies tree with our algorithm. The obtained scenario displays important HGT and related events.

Reconstruction of ancestral regulatory signals along a transcription factor tree
2007
Molecular Biology (Moscow)
A model and an algorithm were developed to reconstruct the ancestral regulatory signals, first and foremost, for DNA-protein interactions, at inner nodes of a transcription factor phylogenetic tree on the basis of the modern signal distribution. The algorithm simultaneously infers the evolutionary scenario as a set of tree edges along which the signal diverged to the greatest extent. The model and algorithm were tested with simulation data and biological findings on the NrdR, MntR, and LacI signals.
