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.
