靶點詳情

功能：

ATP-dependent DNA helicase and primase essential for viral DNA replication and recombination. The helicase moves 5' -> 3' on the lagging strand template, unwinding the DNA duplex ahead of the leading strand polymerase at the replication fork and generating ssDNA for both leading and lagging strand synthesis. ATP or dTTP hydrolysis propels each helicase domain to translocate 2 nt per step sequentially along DNA. Mediates strand transfer when a joint molecule is available and participates in recombinational DNA repair through its role in strand exchange. Primase activity synthesizes short RNA primers at the sequence 5'-GTC-3' on the lagging strand that the polymerase elongates using dNTPs and providing the primase is still present.
