Depositor Comments

Double-stranded DNA specific exonuclease. Initiates at the 3' termini of linear double-stranded DNA with 5' overhangs or blunt ends and 3' overhangs containing less than four bases. Initiates at nicked sites in double-stranded DNA. Catalyzes the removal of nucleotides from linear or nicked double-stranded DNA in the 3' to 5' direction. Ideal for site-directed mutagenesis, preparation of single-stranded DNA for dideoxy sequencing, preparation of nested deletions in double-stranded DNA.

The plasmids in the Open Enzyme collection contain genetic parts and are not functional by themselves. Researchers can clone these enzymes into an expression vector of their choice and then transform into E. coli bacteria for expression and purification.
