We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

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.
