title: Purification and crystallization of the EcoRV restriction endonuclease.
abstract: The type II restriction endonuclease EcoRV purified from a genetically engineered, overproducing strain has been crystallized. Four crystal forms all obtained by precipitation with polyethylene glycol 4000 have been characterized. Two of these are suitable for high resolution structure analysis. Both are orthorhombic, have space group P2(1)2(1)2(1) and have similar unit cell dimensions of a = 58.2 A, b = 71.7 A, c = 130.6 A (form A) and a = 59.9 A, b = 74.5 A, c = 121.8 A (form B). They diffract to about 2A resolution and appear to have one dimer of 2 X 29,000 daltons in the asymmetric unit.
