Taq DNA Polymerase and Thermus Aquaticus

Thermus aquaticus is a thermophilic bacterium known for its heat-resistant enzyme, Taq DNA polymerase, crucial for PCR. Discovered in Yellowstone, it thrives in high temperatures and has a cylindrical shape. Its enzymes, including aldolase and RNA polymerase, are vital for molecular biology. Taq polymerase revolutionized DNA amplification, earning Kary Mullis a Nobel Prize. The commercial use of these enzymes sparked controversy, leading to benefit-sharing agreements with the National Park Service.
