Taq Polymerase is a thermostable DNA Polymerase enzyme with significant processivity that is most commonly used in PCR. The recombinant Taq DNA Polymerase is cloned and expressed in E. coli that shows identical characteristics to native Taq from the thermophilic eubacterium Thermus aquaticus in all aspects of PCR performance. Its terminal transferase activity results in addition of a single nucleotide (adenosine) at the 3' end of the extension product. Taq DNA Polymerase catalyzes the incorporation of dNTPs into DNA in the presence of a DNA template, primer terminus and a cofactor (Magnesium). Taq DNA Polymerase contains a polymerization dependent 5′-3′ exonuclease activity which makes DNA products with A (adenine) overhangs at their 3' end that is important in ligation of the PCR product into the plasmid vector. Despite of having no proof-reading function (as It lacks 3′-5′ exonuclease activity), the enzyme is fully capable to synthesize DNA in vitro with reasonable fidelity. It shows no tendency to mis incorporate nucleotides even after repeated use for cycle sequencing. Recombinant Taq enzyme has a molecular weight of 95-kDa and shows optimal 5’-3’ polymerase activity between 75-80 °C with a half-life of 40 minutes at 95 °C. It can replicate a DNA strand of 1000 bp in less than 10 seconds at 72 °C.
