    摘要: The present invention relates to methods to engineer nicking endonucleases from existing Type IIs restriction endonucleases, and the production of the engineered nicking endonucleases. Two engineering methods are disclosed. One involves inactivating the dimerization function of a Type IIs restriction enzyme using site-directed mutagenesis approach. The other involves replacing the cleavage domain of a Type IIs restriction enzyme with the cleavage domain from a natural occurring nicking endonuclease, N.BstNBI.

    摘要: Methods and a kit are provided for selectively and exponentially amplifying nucleic acids and include the use of a single strand helicase preparation or a thermostable helicase in the absence of a single strand binding protein and a DNA polymerase such that the amplification can be performed isothermally.
