Thermo Scientific Endonuclease V, T. maritima (Endo V) is a 3'-endonuclease involved in DNA repair, which initiates removal of deaminated bases from damaged DNA, including uracil, hypoxanthine, and xanthine.

Endonuclease V is also active toward abasic sites and urea sites, base pair mismatches, flap and pseudo Y structures, and small insertions/deletions in DNA molecules. The cleavage site generated by Endonuclease V is at the second phosphodiester bond 3' to a lesion.


• Optimal activity at temperatures of 65 to 70°C


• High-throughput methods for mutation research
• Studies in mutagenesis and DNA repair
• Mismatch cleavage
• Genotyping


Use of this enzyme in certain applications may be covered by patents and may require a license.

When the enzyme is in excess, the primary nicked products experience a second nicking event on the complementary strand, leading to a double-stranded break. At low concentrations, however, Endonuclease V first nicks a DNA strand at the lesions located closer to the 5'-end of DNA molecule. Single-stranded DNA is cleaved with much lower efficiency. Mg2+ or Mn2+ ions are required for enzyme activity.
