title: Preliminary X-ray data for an N-terminal fragment of rabbit serum transferrin.
abstract: An iron-containing fragment (Mr approximately 39,000) of rabbit serum transferrin has been crystallized from a solution of 25% (w/v) polyethylene glycol 6000, 50 mM-disodium piperazine-N,N'bis(2-ethanesulphonate) adjusted to pH 6.0 at 4 degrees C. The space group is P3(1)21 (or the enantiomorph) with a = b = 66.8(1) A, c = 137.5(3) A and Z = 6. The crystals appear as hexagonal plates, with the unique axis perpendicular to the plate. The crystals, kept at 4 degrees C, are stable in the X-ray beam for at least 130 hours and diffract to better than 1.8 A resolution.
