title: Preliminary characterization of crystals of the protein insecticyanin from the tobacco hornworm Manduca sexta L.
abstract: Crystals of insecticyanin, a blue protein from the haemolymph of the tobacco hornworm Manduca sexta L. have been obtained. They are hexagonal, space group P6(1)22 (or P6(5)22), with unit cell dimensions a = b = 79.1 A, c = 312.1 A. The crystals diffract to 2.5 A resolution, and they are suitable for X-ray diffraction analysis.
