Description:
Due to its thermo-stable nature, DNA polymerase (thermotoga neapolitana) was identified(1) as an enzyme able to withstand the protein-denaturing conditions (high temperature) required during PCR(2). Similar to Escherichia coli DNA polymerase I, but unlike Taq DNA polymerase, Tne DNA polymerase contains both 3'-> 5' and 5'-> 3'- exonulease activity. Therefore it replaced the DNA polymerase from E. coli originally used in PCR (3). Taq's optimum temperature for activity is 75-80°C, with a half-life of 9 minutes at 97.5°C, and can replicate a 1000 bp strand of DNA in less than 10 seconds at 72°C(4).
The DNA products have an A (adenine) overhangs at their 3' ends. This may be useful in TA cloning, whereby a cloning vector (such as a plasmid) that has a T (thymine) 3'- overhang is used, which complements with the A overhang of the PCR product, thus enabling ligation of the PCR product into the plasmid vector.

Application:
- PCR (ordinary and high-throughput)
- Primer Extension
- Microarray Analysis
- Denaturing high performance liquid chromatography (DHPLC)

Source:
