WebFor instance, proofreading Pfu DNA polymerase has fidelity that is 7x that of Taq DNA polymerase, but its synthesis rate is less than half that of Taq polymerase. A breakthrough in processivity was achieved when DNA polymerases were engineered with a strong DNA-binding domain of another protein without compromising polymerase activity (Figure 9 ... DNA polymerase's ability to slide along the DNA template allows increased processivity. There is a dramatic increase in processivity at the replication fork. This increase is facilitated by the DNA polymerase's association with proteins known as the sliding DNA clamp. The clamps are multiple protein subunits … See more A DNA polymerase is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replication and … See more Based on sequence homology, DNA polymerases can be further subdivided into seven different families: A, B, C, D, X, Y, and RT.
