Crystallization and preliminary X-ray diffraction studies of colicin E3 immunity protein.
Immunity protein, an inhibitor of the ribonuclease activity of the protein antibiotic colicin E3, crystallizes in the orthorhombic space group C222 with cell dimensions a = 78.7 A, b = 54.1 A, c = 36.1 A and one molecule of Mr 9800 per asymmetric unit. The crystals are suitable for high resolution X-ray analysis.
