T4 Endonuclease VII

Description:
T4 Endonuclease VII is a DNA junction specific endonuclease (also referred to as a resolvase or a cleavase). T4 Endonuclease VII functions in vivo to resolve branched DNA structures in newly synthesized DNA. It also recognizes mismatches, insertion or deletion loops, gaps, and apurinic/apyrimidinic sites, and creates nicks in the DNA strands at these sites. The wide variety of substrates accepted suggests that T4 Endonuclease VII recognizes changes in the structure or conformation of DNA rather than binding to a specific sequence. It has also been crystallized as a dimer.

Applications:

• enzymatic mutation detection technology (EMD)
• SNP detection
• Resolve Holliday structures in vitro
• Ideal for cleaving DNA heteroduplexes on one strand
