- Аннотация: CheY-like phosphoacceptor (or receiver [REC]) domain is a common module in a variety of response regulators of the bacterial signal transduction systems. In this work, 4,610 response regulators, encoded in complete genomes of 200 bacterial and archaeal species, were identified and classified by their domain architectures. Previously uncharacterized output domains were analyzed and, in some cases, assigned to known domain families. Transcriptional regulators of the OmpR, NarL, and NtrC families were found to comprise almost 60% of all response regulators; transcriptional regulators with other DNA-binding domains (LytTR, AraC, Spo0A, Fis, YcbB, RpoE, and MerR) account for an additional 6%. The remaining one-third is represented by the stand-alone REC domain (?14%) and its combinations with a variety of enzymatic (GGDEF, EAL, HD-GYP, CheB, CheC, PP2C, and HisK), RNA-binding (ANTAR and CsrA), protein- or ligand-binding (PAS, GAF, TPR, CAP_ED, and HPt) domains, or newly described domains of unknown function. The diversity of domain architectures and the abundance of alternative domain combinations suggest that fusions between the REC domain and various output domains is a widespread evolutionary mechanism that allows bacterial cells to regulate transcription, enzyme activity, and/or protein-protein interactions in response to environmental challenges. The complete list of response regulators encoded in each of the 200 analyzed genomes is available online at http://www.ncbi.nlm.nih.gov/Complete_Genomes/RRcensus.html.
