McsB; Catalyzes the specific phosphorylation of arginine residues in a large number of proteins. Is part of the bacterial stress response system. Protein arginine phosphorylation has a physiologically important role and is involved in the regulation of many critical cellular processes, such as protein homeostasis, motility, competence, and stringent and stress responses, by regulating gene expression and protein activity.

Class III stress response-related ATPase; Belongs to the ClpA/ClpB family.

ATP-dependent Clp protease-like (class III stress gene) ClpE; Belongs to the ClpA/ClpB family.

Conserved hypothetical protein YacL; Putative Nucleotide binding protein, PINc.

DNA repair protein RadA; DNA-dependent ATPase involved in processing of recombination intermediates, plays a role in repairing DNA breaks. Stimulates the branch migration of RecA-mediated strand transfer reactions, allowing the 3' invading strand to extend heteroduplex DNA faster. Binds ssDNA in the presence of ADP but not other nucleotides, has ATPase activity that is stimulated by ssDNA and various branched DNA structures, but inhibited by SSB. Does not have RecA's homology-searching function.

Transcriptional regulator; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.

DNA binding protein; Participates in a DNA-damage check-point that is active prior to asymmetric division when DNA is damaged. DisA forms globular foci that rapidly scan along the chromosomes during sporulation, searching for lesions. When a lesion is present, DisA pauses at the lesion site. This triggers a cellular response that culminates in a temporary block in sporulation initiation.

Bipartite response regulator, C-terminal effector; Might take part in the signal recognition particle (SRP) pathway. This is inferred from the conservation of its genetic proximity to ftsY/ffh. May be a regulatory protein.

Putative RNase; Toxic component of a type II toxin-antitoxin (TA) system.
