Abstract
An essentially pure preparation of thermostable RNase H isolated from Thermus flavus is disclosed. In one preferable form of the invention, the RNase H is capable of biological activity after incubation at temperatures equal to or greater than 70.degree. C. for at least ten minutes. The present invention is also a method of digesting RNA polymers that are in duplex form with a DNA molecule. The method comprises exposing the duplex to the isolated thermostable RNase H. The present invention is also a genetic construct capable of expressing a thermostable RNase H.
