Exodeoxyribonuclease III (EC 3.1.11.2, ''Escherichia coli'' exonuclease III, ''E. coli'' exonuclease III, endoribonuclease III) is an
enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different mol ...
that
catalyses the following reaction
: Exonucleolytic cleavage in the 3′- to 5′-direction to yield nucleoside 5′-phosphates
This enzyme has a preference for double-stranded
DNA
Deoxyribonucleic acid (; DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of al ...
