Description
The T4 UvsX Recombinase is derived from the T4 bacteriophage and is a homolog of the RecA/Rad51 family. It plays an important role in the repair of double stranded DNA breaks and the reactivation of replication forks. T4 UvsX recombinase can combine with other DNA binding proteins or cofactors to form nucleic acid protein complexes with single stranded DNA, and polymerize on them to form helical filaments. The latter can bind to double stranded DNA (dsDNA) and initiate chain displacement reactions. T4 UvsX Recombinase can be used for Recombinase Polymerase Amplification (RPA). RPA technology does not require thermal denaturation pre-treatment of the template and can be performed at a constant temperature (37-42℃) with shorter amplification time. Compared with other PCR tec hnologies, RPA reaction requires the following components: recombinant enzyme T4 UvsX Recombinase, recombinant enzyme loading factor T4 UvsY Protein, ssDNA binding protein T4 gp32 Protein, and DNA polymerase (such as Bsu DNA Polymerase, Large Fragment).
