Abstract: | Crystals of human lithostathine, a pancreatic glycoprotein which inhibits the growth and nucleation of calcium carbonate crystals, were grown using PEG 4000 as the precipitating agent. The crystals belong to the hexagonal space group P61 (or its enantiomorph P65) and diffract to 1.55 Å resolution. There is one molecule in the asymmetric unit and the crystals have 39% solvent. © 1995 Wiley-Liss, Inc. |
