Molecular symmetry of fructose-1,6-diphosphatase by X-ray diffraction analysis
B. Soloway and A. McPherson
Large single crystals of rabbit liver fructose-1,6-diphosphatase suitable
for a high resolution structure analysis have been grown from polyethylene
glycol. The space group of these crystals is I222 with a = 75 A, b = 81 A,
and c = 132 A and there are 2 tetrameric molecules in the unit cell. These
crystals have one protein subunit as the crystallographic asymmetric unit
and establish point group symmetry 222 as the molecular symmetry.
