Processivity of TaqDNA polymerase, the Stoffel fragment, Pfu polB, and the hybrid polymerases in salts. Processivities of enzymes in primer extension reactions were determined as described in Materials and Methods, and the dependencies of Pe for enzymes with Taq polymerase catalytic domain on salt concentrations were plotted for NaCl (A), KCl (B), and potassium glutamate (C). The dependencies of Pe for enzymes with Pfu polymerase catalytic domain are collected in D.
