| Protein name | RecName: Full=Flap endonuclease Xni; Short=FEN; EC=3.1.-.-; |
| Gene name | Name=xni; Synonyms=ygdG; |
Comments
[?]
| FUNCTION | Has flap endonuclease activity. During DNA replication, flap endonucleases cleave the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. |
| COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Note=Binds 2 Mg(2+) per subunit. Only one magnesium ion has a direct interaction with the protein, the other interactions are indirect.; |
| COFACTOR | Name=K(+); Xref=ChEBI:CHEBI:29103; Note=Binds 1 K(+) per subunit. The potassium ion strongly increases the affinity for DNA.; |
| SIMILARITY | Belongs to the Xni family. |
