DNA polymerase/3'-5' exonuclease X; Strictly DNA-template-directed DNA polymerase, preferentially acting on DNA structures containing gaps from one to a few nucleotides and bearing a phosphate group at the 5' end of the downstream DNA. The fact that PolX is able to conduct filling of a single-nucleotide gap, allowing further sealing of the resulting nick by a DNA ligase, points to a putative role in base excision repair (BER) during the B.subtilis life cycle. Moreover, also possesses a 3'-5' exonuclease activity able to edit unpaired 3'-termini in a gapped DNA substrate and likely invo [...]

Putative DNA mismatch repair enzyme; Endonuclease that is involved in the suppression of homologous recombination and may therefore have a key role in the control of bacterial genetic diversity; Belongs to the DNA mismatch repair MutS family. MutS2 subfamily.

Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 12065423.

anti-sigma(W) factor; The anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-W (SigW). Holds SigW, its cognate ECF sigma factor, in an inactive form until released by regulated intramembrane proteolysis (RIP). SigW and RsiW mediate cell response to cell wall stress. RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, PrsW) , then within the membrane itself (site-2 protease, S2P [...]

Ribonuclease HIII; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family. RnhC subfamily.

Conserved hypothetical protein; Activator of cell division through the inhibition of FtsZ GTPase activity, therefore promoting FtsZ assembly into bundles of protofilaments necessary for the formation of the division Z ring. It is recruited early at mid-cell but it is not essential for cell division (By similarity); Belongs to the ZapA family. Type 2 subfamily.

Protease required for RsiW anti-sigma(W) degradation; Involved in the degradation of anti-sigma-W factor RsiW. Responsible for Site-1 cleavage of the RsiW anti-sigma factor. This results, after two other proteolytic steps catalyzed by the RasP and ClpXP proteases, in the release of SigW and the transcription activation of the genes under the control of the sigma-W factor. Seems to be responsible for sensing antimicrobial peptides that damage the cell membrane and other agents that cause cell envelope stress. Therefore it is a protease governing regulated intramembrane proteolysis and r [...]

Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.

ferredoxin-NADP+ reductase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the ferredoxin--NADP reductase type 2 family.
