title: Crystallization of complexes of EcoRV endonuclease with cognate and non-cognate DNA fragments.
abstract: Complexes of the type II restriction endonuclease EcoRV with a variety of short, selfcomplementary deoxyoligonucleotides have been crystallized. The best crystals diffract to about 2.7 A resolution and consist of 1:1 complexes between endonuclease dimers and duplexes of the cognate decamer GGGATATCCC containing the hexameric RV recognition sequence GATATC. Crystals with the non-cognate DNA octamer duplexes CGAGCTCG and CGAATTCG diffract to 3.0 and 3.5 A resolution, respectively, and contain two DNA duplexes per enzyme dimer.
