Regulon inference without arbitrary thresholds: three levels of sensitivity

Description: Reconstruction of transcriptional regulatory networks is one of the major challenges facing the bioinformatics community in view of constantly growing number of complete genomes. The comparative genomics approach has been successfully used for the analysis of the transcriptional regulation of many metabolic systems in various bacteria taxa. The key step in this approach is given a position weight matrix, find an optimal threshold for the search of potential binding sites in genomes. In our prev… more

Reference set of regulons in Desulfovibrionales inferred by comparative genomics approach

Description: in this study, we carried out large-scale comparative genomics analysis of regulatory interactions in Desulfovibrio vulgaris and 12 related genomes from Desulfovibrionales order using our recently developed web server RegPredict (http://regpredict.lbl.gov). An overall reference collection of 26 Desulfovibrionales regulogs can be accessed through RegPrecise database (http://regpredict.lbl.gov).

In silico discovery of the dormancy regulons in a number of Actinobacteria genomes

Description: Mycobacterium tuberculosis is a dangerous Actinobacteria infecting nearly one third of the human population. It becomes dormant and phenotypically drug resistant in response to stresses. An important feature of the M. tuberculosis pathogenesis is the prevalence of latent infection without disease, making understanding of the mechanisms used by the bacteria to exist in this state and to switch to metabolically active infectious form a vital problem to consider. M. tuberculosis dormancy is regula… more
