Description:
T7 DNA Polymerase is the mesophilic, highly processive, and replicative DNA polymerase from bacteriophage T7. It is respons
IBL
e 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 respons
IBL
e 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.
