Taq Ligase is thermostable DNA ligase from the thermophilic bacterium Thermus aquaticus cloned to E. coli cells. This enzyme is able to be stable and active at much higher temperatures than conventional DNA ligases and could be used at PCR conditions. However, it cannot be used to replace T4 DNA Ligase in most cloning methods due to insufficient activity at low temperatures where 2- and 4-base cohesive ends form stable duplexes or blunt ends.
Taq Ligase is a 74 kDa Thermus aquaticus ligase protein catalyzing the NAD-dependent ligation of adjacent 3-hydroxyl and 5-phosphate termini in duplex DNA structures. It does not exhibit activity on blunt ends or RNA substrates. This enzyme is active in a variety of DNA polymerase buffers within a pH range of 7-8.
