Host factor Hfq; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs (By similarity). Contributes to long-term survival under nutrient deprivation, to stationary phase-dependent hydrogen peroxide and acid stress resistance and is required for prolonged survival in the intracellular environment of the host macrophage. Therefore, contributes not only to a generalized stress response in stationary p [...]

Endonuclease III; DNA repair enzyme that has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases various damaged pyrimidines from DNA by cleaving the N-glycosidic bond, leaving an AP (apurinic/apyrimidinic) site. The AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'- phosphate.

DNA polymerase III, beta chain:Inorganic pyrophosphatase; Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta chain is re [...]

HhH-GPD.

HhH-GPD:Iron-sulfur cluster loop:Endonuclease III, FCL:A/G-specific adenine glycosylase MutY; Adenine glycosylase active on G-A mispairs.

Pseudouridine synthase; High mobility group proteins HMG-I and HMG-Y:Pseudouridine synthase, Rsu:RNA-binding S4:Pseudouridine synthase; Belongs to the pseudouridine synthase RsuA family.

Replication factor C conserved domain.

Conserved hypothetical protein; Participates in the translocation of lipoproteins from the inner membrane to the outer membrane. Only forms a complex with a lipoprotein if the residue after the N-terminal Cys is not an aspartate (The Asp acts as a targeting signal to indicate that the lipoprotein should stay in the inner membrane).

AP endonuclease, family 1:Exodeoxyribonuclease III xth:Endonuclease/exonuclease/phosphatase family.
