| Description : |
Exonuclease III 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. Exonuclease III breaks phosphodiester bonds on the 5′ side of AP sites in both dsDNA and ssDNA, removes 3′ terminal groups on dsDNA, increases MutY turnover, and efficiently degrades 3′ recessed but not 3′ protruding DNA ends (creating 5′ overhangs). Exo III removes a limited number of nucleotides per binding event, resulting in coordinated progressive deletions within the population of DNA molecules. |
