General annotation (Comments)

Function

5'->3' double-stranded DNA exonuclease involved in mismatch repair and eventually also in mitotic recombination between direct repeats. Also has a minor role in the correction of large DNA mismatches that occur in the heteroduplex DNA during meiotic recombination at the HIS4 locus. Ref.1 Ref.5 Ref.6 Ref.8

Cofactor

Binds 2 magnesium ions per subunit. They probably participate in the reaction catalyzed by the enzyme. May bind an additional third magnesium ion after substrate binding By similarity.

Enzyme regulation

Inactivated by calcium and zinc ions.

Subunit structure

Interacts with mismatch repair protein MSH2. Ref.1

Subcellular location

Nucleus Potential.

Miscellaneous

Present with 672 molecules/cell in log phase SD medium.

Sequence similarities

Belongs to the XPG/RAD2 endonuclease family. EXO1 subfamily.
