title: Preliminary X-ray crystallographic studies of pig kidney fructose-1,6-bisphosphatase.
abstract: 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.
