Introduction | Endonuclease III (nth) is a DNA repair enzyme which has both DNA N-glycosylase activity and AP-lyase activity. The DNA N-glycosylase activity releases numerous damaged pyrimidines from DNA by cleaving the N-glycosidic bond and leaving an AP (apurinic/apyrimidinic) site. This AP-lyase activity cleaves the phosphodiester bond 3' to the AP site by a beta-elimination, thus leaving a 3'-terminal unsaturated sµgar and a product with a terminal 5'-phosphate. |
Synonyms | DNA-(apurinic or apyrimidinic site) lyase, b1633, JW1625. |
Source | Escherichia Coli. |
Physical Appearance | Sterile Filtered colorless solution. |
Formulation | The NTH solution (0.5mg/1ml) contains 20mM Tris-HCl buffer (pH8.0), 0.1M NaCl, 1mM DTT, 0.1mM PMSF and 40% glycerol. |
