Collections of regulogs classified by RNA regulatory elements

Each RNA family collection organizes all reconstructed regulogs for a given family of regulatory RNA across different taxonomic groups of microorganisms. Genomic distribution and repertoires of controlled genes (regulons) were analyzed for 36 families of regulatory RNAs including 15 metabolite-sensing riboswitches, 6 ribosomal operons leadears, 4 amino acid-responsive attenuators, and multiple cis-acting regulatory RNAs of yet unknown regulatory mechanism. The large collection of T-box regulons for amino acid metabolism was classified by amino acid specifcities based on detailed analysis of T-box sequences. The RNA family regulon collections are valuable for evolutionary analysis of regulatory RNAs and their regulons from the same RNA family.
