摘要:
A Herpes simplex virus (HSV) recombinase comprises a purified or isolated alkaline nuclease and a single stranded DNA binding protein. In HSV-1, the alkaline nuclease is the UL12 protein and the single stranded DNA binding protein is the ICP8 protein. The HSV recombinase can be purified from an in vitro expression system or can be expressed in an appropriate vector or vectors wherein the DNAs encoding the polypeptides are operatively linked to expression control sequences. Methods of use of the HSV recombinase include cloning, treating cells and organisms, and producing transgenic animals. The HSV recombinase can be in the form of a kit useful for cloning.
摘要:
UmuC is found to be a translesion replication DNA polymerase which replicates in the presence of UmuD′, RecA and SSB through a DNA lesion of damaged DNA molecule and which is found to be highly mutagenic during in vitro gap-filling replication. A method for replicating a DNA molecule with DNA lesion damage and a method for mutagenesis of a DNA molecule are provided.
