Regulator of genetic competence; Required for the development of competence.

Competence transcription factor (CTF); A master regulator required for the expression of late competence genes including comC, comE, comG and the bdbDC operon. Receives signals from SrfA, and possibly other regulatory COM genes, and transduces these signals to the late COM genes. Represses transcription of rok. May repress expression of a few genes.

ATP-dependent Clp protease proteolytic subunit; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a limited peptidase activity in the absence of ATP-binding subunits ClpC, ClpE or ClpX. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins (By similarity). ClpXP is involved in the complete degradation of the site-2 clipped anti-sigma-W factor RsiW. This results in the release of SigW and the transcriptional activation of genes under the control of the sigma-W factor. Probably the major protease that degrades prot [...]

Protein unfolding ATPase required for presentation of proteins to proteases; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP (By similarity). Probably the major protease that degrades proteins tagged by trans-translation.

Putative thiol management oxidoreductase component; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.

Protein tyrosine kinase; Catalyzes the specific phosphorylation of arginine residues in a large number of proteins. Is part of the bacterial stress response system, where it is involved in regulating the global heat shock repressor CtsR; phosphorylates arginine residues in the winged helix- turn-helix domain of CtsR, thereby preventing its binding to DNA and consequently inducing the expression of repressed genes. The transcriptional repressor HrcA, the chaperone GroEL, the unfoldase ClpC, together with several ribosomal subunits, represent other physiological targets of McsB under str [...]

Redox-sensitive regulator enzyme; Interferes with activator-stimulated transcription by interaction with the RNA polymerase alpha-CTD. May function to globally reduce transcription of genes involved in growth- and development- promoting processes and to increase transcription of genes involved in thiol homeostasis, during periods of extreme stress. Negatively affects competence and sporulation. Its degradation by the MecA/ClpXP complex is needed for competence development; Belongs to the ArsC family. Spx subfamily.

Protein involved in establishment of DNA transport in competence; Required for optimal transformation.

Transcriptional regulator for transition state genes; Ambiactive repressor and activator of the transcription of genes expressed during the transition state between vegetative growth and the onset of stationary phase and sporulation. It controls the expression of genes spovG and tycA. AbrB binds to the tycA promoter region at two A- and T-rich sites, it may be the sole repressor of tycA transcription; To B.subtilis Abh and SpoVT.
