| UniProt functional annotation for P0A6C1 | |||
| UniProt code: P0A6C1. |
| Organism: | Escherichia coli (strain K12). | |
| Taxonomy: | Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia. | |
| Function: | Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating a 3'-hydroxyl group and a 5'-terminal sugar phosphate. It preferentially attacks modified AP sites created by bleomycin and neocarzinostatin. | |
| Catalytic activity: | Reaction=Endonucleolytic cleavage to 5'-phosphooligonucleotide end- products.; EC=3.1.21.2; | |
| Cofactor: | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Note=Binds 3 Zn(2+) ions. Can also bind Mn(2+) ions.; | |
| Subunit: | Monomer. | |
| Induction: | Endonuclease IV is induced by agents which generate superoxide radical anions. | |
| Similarity: | Belongs to the AP endonuclease 2 family. {ECO:0000255|HAMAP-Rule:MF_00152, ECO:0000305}. | |
