X-RAY DIFFRACTION	?	?	FOR THE CRYSTALLIZATION OF THE NIRDL-FE-URO III CO-COMPLEX, NIRDL (7 MG/ML) WAS INCUBATED 30 MIN ON ICE WITH 0.5 MM FE-URO III (DISSOLVED IN 50 % DMSO) PRIOR TO CRYSTAL SETUP. PROTEIN-FE-URO III WAS MIXED WITH EQUAL AMOUNTS OF PRECIPITANT SOLUTION (27 % (V/V) MPD, 0.1 M MES, PH 5.5, AND 9.95 MM SPERMIDINE). CRYSTALS WERE CRYO-PROTECTED WITH 25-33 % (V/V) GLYCEROL OR ADDITIONAL 33 % (V/V) MPD PRIOR TO FLASH FREEZING IN LIQUID NITROGEN.
