A thermostable enzyme from the hyperthermophilic sul-phate-reducing archaeon, Archaeoglobus fulgidus,was expressed and characterized on the assumption that it is homologous to exonuclease III from Escherichia coli. Sequence similaritydatabase searcheswere performedbased on the amino acid sequence of exonuclease III. The 774bp longgenewas isolated froma culture sample andcloned into different vectors.
