Klenow fragment: Definition and Applications Definition: It is the large fragment of DNA polymerase I enzyme of E.coli produced by the proteolytic cleavage of DNA pol I by protease subtilisin.

First reported in 1970, it retains the 5' → 3' polymerase activity and the 3’ → 5’ exonuclease activity for removal of precoding nucleotides and proofreading, but loses its 5' → 3' exonuclease activity. The Klenow Fragment corresponds to the 70-kDa cleavage product of the E. coli DNA Polymerase I with the protease, subtilisin.It lacks the 5’-3’ exonuclease activity of DNA Pol I, a feature that makes the enzyme unsuitable in molecular biology purposes.
