Endonuclease IV (Nfo) from Escherichia coli is a 32-kD metalloprotein that aids in the repair of damaged DNA. The enzyme functions both as an apurinic/apyrimidinic nuclease (1) and as a 3′-terminal di-esterase (1-4). Its 3′-terminal di-esterase activity is important in the repair of DNA strand breaks generated by oxidation and ionic radiation (2, 3). In such events, the strand breaks terminate with either a 3′ phosphate or a deoxyribose fragment, preventing repair by DNA polymerase I or DNA ligase. Endonuclease IV removes the blocking groups, leaving a free 3′-hydroxyl terminus. This enzyme does not have detectable associated exonuclease or DNA N-glycosylase activity (1).Applications• Single cell gel electrophoresis (Comet assay) (5, 6)• Alkaline elution (7)• Alkaline unwinding (8)Product SourceE. coli BL21 (DE3) strain expressing E. coli Endonuclease IV gene.Product Includes• Endonuclease IV (Nfo)• 10x Endonuclease IV reaction buffer
