mutM | formamidopyrimidine-DNA glycosylase; Involved in base excision repair of DNA damaged by oxidation or by mutagenic agents. Acts as DNA glycosylase that recognizes and removes damaged bases. Has a preference for oxidized purines, such as 7,8-dihydro-8-oxoguanine (8-oxoG). Has AP (apurinic/apyrimidinic) lyase activity and introduces nicks in the DNA strand. Cleaves the DNA backbone by beta-delta elimination to generate a single-strand break at the site of the removed base with both 3'- and 5'-phosphates. (273 aa) | ||||
ENX36168.1 | Hypothetical protein; Belongs to the DNA glycosylase MPG family. (188 aa) | ||||
ENX39909.1 | Hypothetical protein. (184 aa) | ||||
ENX39912.1 | A/G-specific adenine glycosylase; Adenine glycosylase active on G-A mispairs. (345 aa) | ||||
ENX39987.1 | Exodeoxyribonuclease III. (274 aa) | ||||
ENX40018.1 | single-stranded-DNA-specific exonuclease RecJ. (566 aa) | ||||
ENX40229.1 | Hypothetical protein. (263 aa) | ||||
ENX39577.1 | Hypothetical protein. (81 aa) | ||||
polA | DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family. (921 aa) | ||||
ENX39719.1 | Hypothetical protein; Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) and O4-methylthymine (O4-MeT) in DNA. Repairs the methylated nucleobase in DNA by stoichiometrically transferring the methyl group to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated. (162 aa) | ||||
ligA | DNA ligase; DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA; Belongs to the NAD-dependent DNA ligase family. LigA subfamily. (675 aa) | ||||
ENX36987.1 | Hypothetical protein. (196 aa) | ||||
ung | uracil-DNA glycosylase; Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or due to deamination of cytosine. (237 aa) | ||||
nth | 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. (228 aa) |
