A new type II restriction endonuclease, Ssh AI, 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 Sau I from Streptomyces aureofaciens and Bsu 361 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.
