Pfu DNA polymeraseenzyme is found in the hyperthermophilic archaeonPyrococcus furiosus， where it functions in vivoto replicate the organism’s DNA. In vitro， Pfu is used to swiftly amplify DNAin the Polymerase Chain Reaction， where the enzyme serves the central function of copying a new strand of DNA during each extension step. Pfu DNA polymerase has superior thermostability and ’proofreading’ properties compared to other thermostable polymerases. Unlike Taq DNA polymerase， Pfu DNA polymerase possesses 3’ to 5’ exonuclease proof reading activity， meaning that it works its way along the DNA from the 5’ endto the 3’ endand corrects nucleotidemisin corporation errors. Pfu DNA polymerase-generated PCRfragments will have fewer errors than Taq-generated PCR inserts. As a result， Pfu is more commonly used for molecular cloning of PCR fragments than the historically popular Taq. Pfu DNA polymerase is superior for techniques that require high-fidelity DNA synthesis， but can also be used in conjunction with Taq polymerase to obtain the fidelity of Pfu with the speed of Taq polymerase activity.
