Endonuclease IV (E.coli)
EBT-3061
1,000 unit (10 unit/㎕)
100,000
DESCRIPTION
Endonuclease IV is a metalloenzyme that functions in vivo to repair free-radical damage in DNA and cleaves the phosphodiester bond 5' to the lesion generating a hydroxyl group at the 3'-terminus and a deoxyribose 5´-phosphate at the 5´ terminus. The enzyme also has a 3´ -diesterease activity and possesses a 3‘ to 5' exonuclease activity. Its progression on substrates is sensitive to ionic strength, metal ions, EDTA, and reducing conditions. Endonuclease IV is expressed and purified from E.coli.

Applications
- Studies of DNA damage and repair
- DNA structure and SNP analysis
- Antitumor drug evaluation
