	FRODO, INSIGHT, SCTPL2				1			THE DEPOSITED STRUCTURE CONTAINS ONLY CA ATOMS. THE IGM COORDINATES ARE PROVIDED FROM AN EARLY STUDY IN WHICH A MANUAL FIT METHOD BASED ON KNOWN CRYSTAL STRUCTURES FOR IGG WAS USED TO DETERMINE STRUCTURES FOR INTACT IGM AND ITS FAB, FAB'2, FC5 AND IGM-S MONOMER SUBUNITS. THESE CRYSTAL STRUCTURES ORIGINATED FROM HUMAN FAB KOL (PDB CODE 2FB4) AND HUMAN FC (PDB CODE 1FC1). THIS PROCEDURE IS APPROXIMATE AND THE IGM MODEL IS NOT CONSIDERED TO BE OPTIMAL OR REFINED AGAINST THE X-RAY SCATTERING DATA.
