  • T4 pyrimidine DNA glycosylase
  • Bifunctional DNA glycosylase with DNA N-glycosylase and AP lyase activities
  • The N-glycosylase activity releases cis-syn cyclobutane pyrimidine dimers, including T^T, T^C and C^C, generating an AP site. The AP lyase activity cleaves an AP site via β-elimination, creating a 1 nucleotide DNA gap with 3'-α, β-unsaturated aldehyde and 5'-phosphate termini.
  • Also known as T4 Endonuclease V

    What are endonucleases and their applications?
T4 PDG (pyrimidine dimer glycosylase) has both DNA glycosylase and APlyase activity. The 16 kd protein recognizes cis-syn-cyclobutane pyrimidine dimers caused by UV irradiation. The enzyme cleaves the glycosyl bond of the 5´ end of the pyrimidine dimer and the endonucleolytic activity cleaves the phosphodiester bond at the AP site.
Product Source
Purified from an E. coli strain carrying a plasmid encoding T4 denV gene.

Properties & Usage

Unit Definition

One unit is defined as the amount of enzyme that catalyzes the conversion of 0.5 µg of UV irradiated supercoiled pUC19 DNA to > 95% nicked plasmid in a total reaction volume of 20 µl in 30 minutes at 37°C. Nicking is assessed by agarose gel electrophoresis. Irradiated plasmid contains an average of 3-5 pyrimidine dimers.

Materials Sold Separately
Notes
  • Warm buffer to room temperature, as it precipitates at 4°C.
  • The enzyme has 100% activity in NEBuffer 4 (NEB #B7004) and 75% activity in NEBuffers 1-3 (NEB #B7001, NEB #B7002, NEB #B7003).
  • For best results, incubation time should be 30 minutes or less.
  • After the reaction, addition of SDS to a final concentration of 0.5%, or 1µl phenol, in 6X Loading dye to the sample before running the gel will improve electrophoresis by dissociating the protein from the DNA.
