title: SshAI restriction endonuclease from Salmonella shikmonah.
abstract: A new type II restriction endonuclease, SshAI, was purified from Salmonella shikmonah TK139 of kangaroo origin. The recognition and cleavage specificity of Ssh AI was determined to be 5'-CC/TNAGG-3', identical to that of SauI from Streptomyces aureofaciens and Bsu36I from Bacillus subtilis. Based on closely related and in part overlapping recognition specificities of Ssh AI and other restriction endonucleases, a close evolutionary relationship is proposed for all known Salmonella restriction endonucleases.
