PROTEIN WAS CRYSTALLIZED FROM 0.1 M HEPES, PH 7.2 1MM CACL2, 1MM MNCL2 AND 0.15 M NACL

RATHER THAN PROTEIN-PROTEIN CONTACTS, THE DOMINANT FORCE IN THESE CRYSTALS IS SACCHARIDE-PROTEIN CROSS-LINKING WHICH RESULTS IN LARGE SOLVENT FILLED CHANNELS.
THESE COORDINATES ARE OF SBA BOUND TO A BIANTENNARY PENTASACCHARIDE WITH A 3,6 LINKAGE TO THE CORE GALACTOSE.
