== Publication Abstract from PubMed ==

The crystal structure of the dimeric PvuII restriction endonuclease (R.PvuII) has been determined at a resolution of 2.4A. The protein has a mixed alpha/beta architecture and consists of two subdomains. Despite a lack of sequence homology, extensive structural similarities exist between one R.PvuII subdomain and the DNA-binding subdomain of EcoRV endonuclease (R.EcoRV); the dimerization subdomains are unrelated. Within the similar domains, flexible segments of R.PvuII are topologically equivalent to the DNA-binding turns of R.EcoRV; potential catalytic residues can be deduced from the structural similarities to R.EcoRV. Conformational flexibility is important for the interaction with DNA. A possible classification of endonuclease structures on the basis of the positions of the scissile phosphates is discussed.
