Abstract
Single crystals of ribonuclease I from Escherichia coli have been obtained by the vapor diffusion method. The crystals belong to the tetragonal space group P4(1)2(1)2 or its enantiomer P4(3)2(1)2 and have cell parameters a = b = 119.01 A and c = 34.40 A. There is one 27,000 dalton monomer in the asymmetric unit. The crystals diffract to beyond 3.0 A resolution.
