The Type I and III Restriction Endonucleases: Structural Elements in Molecular Motors that Process ase, ATPase and DNA translocase. It has been demonstrated that ATP-dependent protein motion along DNA is necessary for endonuclease activity. Studies have shown that Type I enzymes remain bound to their recognition sites whilst simultaneously translocating adjacent non-specific dsDNA past a stationa

The Integration of Recognition and Cleavage: X-Ray Structures of Pre-Transition State Complex, Postis of DNA(at 24 ° C and pH 7.4) was estimated at 5.7×10. S. (.; .; .); more recently, Radzicka and Wolfenden have estimated this value as 1.7xl0. S.. (.).This corresponds to an estimated half-life of 130,000 years for a DNA phosphodiester bond in solution, placing DNAhydrolysis among the slowest of

Structure and Function of EcoRV Endonuclease,nt-ended fashion. Like most of the restriction enzymes used as tools in recombinant DNA technology it can be considered as a simple hydrolytic enzyme of relatively small size with precisely defined substrate specificity and the rather common requirement for Mg. ions. Yet, these apparently simple pre

Structure and Function of the Tetrameric Restriction Enzymes,, within or close to their recognition sites (.). Around 3500 species, from variety of bacteria with nearly 240 differing specificities, have now been characterized (.). Most of the sequences recognized by Type II restriction endonucleases are palindromic, i. e., possess a twofold rotational axis of
