Endonucleases that generate double-strand breaks in DNA often possess two identical subunits related by rotational symmetry, arranged so that the active sites from each subunit act on opposite DNA strands. In contrast to many endonucleases, Type IIP restriction enzyme BcnI, which recognizes the pseudopalindromic sequence 5'-CCSGG-3' (where S stands for C or(More)
Unlike orthodox Type II restriction endonucleases that are homodimers and interact with the palindromic 4-8-bp DNA sequences, BcnI is a monomer which has a single active site but cuts both DNA strands within the 5'-CC↓CGG-3'/3'-GGG↓CC-5' target site ('↓' designates the cleavage position). Therefore, after cutting the first strand, the BcnI monomer must(More)
