TIGRFAM: exodeoxyribonuclease III exodeoxyribonuclease III Xth; PFAM: Endonuclease/exonuclease/phosphatase; KEGG: bms:BR0873 exodeoxyribonuclease III.

Endonuclease III / DNA-(apurinic or apyrimidinic site) lyase; 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 subunit; 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 required for initiation of [...]

A/G-specific DNA-adenine glycosylase; Adenine glycosylase active on G-A mispairs.

KEGG: ret:RHE_PE00063 putative hydrolase protein.

RNA-binding protein 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. Belongs to the Hfq family.

TIGRFAM: Pseudouridine synthase, Rsu; PFAM: RNA-binding S4 pseudouridine synthase; KEGG: mlo:mlr8253 ribosomal large subunit pseudouridine synthase B; Belongs to the pseudouridine synthase RsuA family.

DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
