Multiple stable crystal forms of two lipases from the fungus Geotrichum candidum have been obtained. The diffraction pattern extends to beyond 2.0 A resolution. Similarity of the cell dimensions of various forms suggested similar packing of molecules in different crystals. This was confirmed by rotation function results. Four heavy-atoms derivatives have been identified.
