Structure of Taq DNA polymerase

A polymerase is an enzyme (EC that synthesizes long chains of polymers or nucleic acids. DNA polymerase and RNA polymerase are used to assemble DNA and RNA molecules, respectively, by copying a DNA template strand using base-pairing interactions or RNA by half ladder replication.

A polymerase from the thermophilic bacterium, Thermus aquaticus (Taq) (PDB 1BGX, EC is used in the polymerase chain reaction, an important technique of molecular biology.

Other well-known polymerases include:
