THESE ARE RE-REFINED COORDINATES OF THE PREVIOUS WWPDB SUBMISSION 1TY5. THE STARTING MODEL WAS A 2.4 ANGSTROM STRUCTURE WITH A DIFFERENT BOUND LIGAND. THE MODEL IS REFINED TO LOWER RFREE. ONE SEQUENCE MISTAKE IN THE AIIB SUBUNIT IS CORRECTED. MORE OF BETA SUBUNIT DOMAIN I-EGF1 IS BUILT. THE ARRANGEMENT OF ATOMS AT CENTERS IN THE LIGAND THAT ARE FREE TO REARRANGE IN SOLVENT IS CHANGED. MISTAKES IN CARBOHYDRATE ANOMERIC LINKAGES ARE ALSO CORRECTED.
