Deoxydecanucleotides having a recognition sequence of Bgl II and Sau 3AI, and their 7-deazaadenine analogs were synthesized. The decanucleotides containing 7-deazaadenine in place of adenine were partially resistant to the hydrolysis by Sau 3AI and strongly resistant to that by Bgl II. A new hypothesis on the mode of recognition and cleavage of specific nucleotide sequences by Bgl II, recognizing one strand and cleaving the other strand, is presented.
