Class II restriction endonuclease KspI and a process for obtaining it

摘要

The present invention provides a restriction endonuclease which recognizes palindromic sequences where C* is methylated, and cleaves these sequences at the position indicated by the arrows. This endonuclease is preferably from a microorganism of the genus Kluyvera. The present invention also provides a process for obtaining this new restriction endonuclease and a method for using the endonuclease.
