Description
Taq DNA Polymerase is a thermostable enzyme that synthesizes DNA from single-stranded templates in the presence of dNTPs and a primer. The enzyme consists of a single polypeptide with a molecular weight of 94 kDa. It has a 5´→3´ DNA polymerase activity and a 5´→3´ exonuclease activity.
One unit of Taq DNA Polymerase is the amount of enzyme required to incorporate 10 nmoles of deoxyribonucleotide into DNA in 30 min at 74°C.
