Crystallization and characterization of the recombinant human Clara cell 10-kDa protein.
Crystals of recombinant human Clara cell 10-kDa protein were grown both from ammonium sulfate and polyethylene glycol (PEG) solutions. Crystals grown from ammonium sulfate solution have been characterized by X-ray diffraction studies as monoclinic with the space group C2 and lattice constants a = 69.2 A, b = 83.0 A, c = 58.3 A, and beta = 99.7 degrees. The monoclinic crystals diffract to beyond 2.5 A. Some of the crystals grown from PEG were of a similar habit to those grown from ammonium sulfate, but others were triclinic with the space group P1 and cell constants a = 40.3 A, b = 46.3 A, c = 51.3 A, alpha = 117.7 degrees, beta = 102.3 degrees, and gamma = 71.4 degrees. These crystals diffract to beyond 3.2 A.
