A new crystal form of restriction endonuclease EcoRII that diffracts to 2.8 A resolution.
EcoRII, a type IIe restriction endonuclease, has been crystallized in space group P2(1), with unit-cell parameters a = 58.3, b = 127.8, c = 59.9 A, beta = 91.4 degrees. There are two monomers in the asymmetric unit and the solvent content is estimated to be 49% by volume. The crystals diffract to 2.8 A resolution, which is much higher than that of the previously reported cubic crystal form, which diffracted to 4 A resolution.
