Description:
T7 DNA Polymerase is a mesophilic, highly processive, and replicative DNA polymerase from bacteriophage T7. It is responsible for the rapid and accurate replication of the virus genome during its infection cycle. T7 DNA Polymerase is a two subunit protein that consists of a polymerase domain (gene 5 from the T7 bacteriophage) and a processivity factor (E. coli trxA gene thioredoxin) (1, 2). The enzyme possesses a powerful (3' -> 5') nuclease activity that acts on both single and double stranded DNA and appears to be responsible for the high fidelity of this enzyme and prevents strand displacement synthesis(3,4,5).

Specific Activity: 10,000U/mg

Application:
Second strand synthesis in site-directed mutagenesis protocols

Source:
A recombinant E. coli strain carrying the bacteriophage T7 gene 5.

Unit Definition:
1 unit is defined as the amount of polymerase required to convert 10 nmol of total dNTPs into acid insoluble material in 30 minutes at 37°C.
