T4 UvsY Protein (from E. coli)
Lieferant: G Bioscienes
T4 recombination mediator protein, UvsY plays important roles in homologous recombination (HR). During HR, the UvsX recombinase competes with the prebound single-stranded binding protein gp32 for DNA-binding sites and UvsY stimulates this filament nucleation event.
- Product source: E. coli cells expressing T4 UvsY gene
- Storage temperature: −20 °C
- Quality control assays: UvsY is free from detectable nuclease contamination
UvsY stimulates the DNA-dependent ATPase activity of UvsX, lowers the critical concentration of UvsX that is required for activity, and promotes strand exchange. UvsY efficiently promotes the UvsX-catalysed strand invasion reaction by recruiting to ssDNA-gp32 complexes, promotes the release of gp32, and favors the binding of UvsX.
