Specific function: Major apurinic-apyrimidinic endonuclease of E.coli. It removes the damaged DNA at cytosines and guanines by cleaving on the 3'-side of the AP site by a beta-elimination reaction. It exhibits 3'-5'-exonuclease, 3'-phosphomonoesterase, 3'-repair diesterase

COG id: COG0708

COG function: function code L; Exonuclease III

Gene ontology:

Cell location: Cytoplasm [C]

Metaboloic importance: Non_Essential [C]

Operon status: Not Known

Operon components: None

Similarity: Belongs to the DNA repair enzymes AP/ExoA family [H]
