Product Description

Product Description

Exonuclease Ill

      Catalyzes the stepwise removal of mononucleotides from 3'-hydroxyl termini of duplex DNA. A limited number of nucleotides are removed during each binding event, resulting in coordinated progressive deletions within the population of DNA molecules . Exonuclease Ill has also been reported to have RNase H, 3'-phosphatase and AP-endonuclease activities . 
      The preferred substrates are blunt or recessed 3'-termini, although the enzyme also acts at nicks in duplex DNA to produce single-strand gaps. 3'-protruding termini are resistant to cleavage; the degree of resistance depends on the length of the exten­sion,with extensions 4 bases or longer being essentially resistant to cleavage. 
     Exonuclease activity depends partially on helical structure and displays sequence dependence (C>A=T>G). Temperature, salt concentration and the ratio of enzyme to DNA greatly affect enzyme activity, requiring reaction conditions to be tailored to specific applications. 

Applications
1. Unidirectional nested deletions
2. Site-directed mutagenesis
3. Preparation of strand-specific probes
4.Preparation of single-stranded substrates for dideoxy sequencing Peformance
