  • In vitro recombination


  • Exonuclease III (ExoIII) of E. coli is a 31 kDa monomeric, globular protein combining multiple catalytic activities in one active site. It acts on doublestranded (ds) DNA as a 3'-5' exonuclease, a 3'- phosphomonoesterase, an apurinic/apyrimidimic (AP) sites specific endonuclease and an exonucleolytic ribonuclease H. Of particular interest for molecular biological methods is its exonucleolytic activity, removing 5'-mononucleotides from the 3'-hydroxyl ends of ds DNA, leaving protruding 5'-termini. Its catalytic rate can be adjusted by temperature and NaCl concentration and thus allows for the generation of single-stranded DNA templates for sequencing or recombination methods. Recombinant Exonuclease III-T is an engineered exonuclease III with improved temperature resistance.
