Description

Description:
Exonuclease III (E. coli) is a 3′ -> 5′ exonuclease which acts by digesting one strand of a dsDNA duplex at a time or digesting the RNA strand of an RNA-DNA heteroduplex(1,2). Exonuclease III (E. coli) breaks phosphodiester bonds on the 5′-side of AP sites in both dsDNA and ssDNA(3). It removes 3′-terminal groups on dsDNA(3), increases MutY turnover(4), and efficiently degrades 3′-recessed but not 3′ protruding DNA ends (creating 5′-overhangs)(5). Exonuclease III (E. coli) removes a limited number of nucleotides per binding event, resulting in coordinated progressive deletions within the population of DNA molecules(1).

Specific Activity:
150,000 U/mg

Application:
Degrades excess single-stranded primer oligonucleotides from a reaction mixture containing double-stranded extension products.

Source:
Purified from a strain of E. coli that expresses the recombinant Exonuclease III gene.
