The 5'-exonuclease domains of the DNA polymerase I proteins of Eubacteria and the FEN1 proteins of Eukarya and Archaea are members of a family of structure-specific 5'-exonucleases with similar function but limited sequence similarity. Their physiological role is to remove the displaced 5' strands created by DNA polymerase during displacement synthesis, thereby creating a substrate for DNA ligase. In this paper, we define the substrate requirements for the 5'-exonuclease enzymes from Thermus… CONTINUE READING
