T4 UvsX DNA Recombinase
Homologous recombination is important for the error-free repair of DNA double-strand breaks and for replication fork restart. Recombinases of the RecA/RAD51 family perform the central catalytic role in this process. UvsX recombinase is the RecA/Rad51 ortholog of bacteriophage T4. T4 UvsX DNA Recombinase and other recombinases form presynaptic filaments on ssDNA that are activated to search for homology in dsDNA and to perform DNA strand exchange (1-3).
The physical purity of this enzyme is ≥98% as assessed by SDS-PAGE with Coomassie® blue staining.
