E7RY93 · E7RY93_9BURK

Function

function

Degrades single-stranded DNA (ssDNA) in a highly processive manner. Also functions as a DNA deoxyribophosphodiesterase that releases deoxyribose-phosphate moieties following the cleavage of DNA at an apurinic/apyrimidinic (AP) site by either an AP endonuclease or AP lyase.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Catalytic activity

  • Exonucleolytic cleavage in the 3'- to 5'-direction to yield nucleoside 5'-phosphates.
    EC:3.1.11.1 (UniProtKB | ENZYME | Rhea)

Cofactor

Mg2+ (UniProtKB | Rhea| CHEBI:18420 )

Note: Binds 2 Mg2+ ions per monomer.
