Preliminary x-ray data have been obtained from large single crystals of pig
kidney fructose-1,6-bisphosphatase, grown from polyethylene glycol. The
crystals have the symmetry of space group P3(1)21 or its enantiomorph
P3(2)21, contain two subunits of the 146,000-dalton tetramer/asymmetric
unit, and diffract to 2.9-A resolution on still photographs. The unit cell
dimensions are a = b = 132.5 A and c = 68.0 A. Small single crystals have
been grown in the presence of the inhibitor fructose 2,6-bisphosphate, with
and without the allosteric effector AMP added. Crystals grown in the
presence of both ligands are isomorphous with native crystals and generate
diffraction patterns that show significant intensity changes.
