Taq DNA Polymerase was originally isolated from the thermophilic bacterium Thermus aquaticus. The enzyme is thermostable; it replicates DNA at 74°C and remains functional even after incubation at 95°C. It is used, in vitro, to extend a DNA primer using DNA as a template.
Taq DNA Polymerase is a monomeric enzyme with a molecular weight of 94,000Da. The enzyme includes a 5`->3` polymerase activity and a 5`->3` exonuclease activity. Taq DNA Polymerase lacks a 3`->5` exonuclease (proofreading) activity, and will incorporate a deoxynucleotide (often an adenosine) in a template independent manner on the 3` end of the new DNA strand. In in vitro assays, Taq DNA Polymerase misincorporates a base every 104-105 bases.
