Difficulties encountered in searching for two tetramers of human glucose 6-phosphate dehydrogenase (Canton variant) using a bacterial G6PD dimer as model were resolved by finding a tetramer in a simpler crystal form and using a tetramer search model. The human G6PD subunit was a suitable model to solve a deletion mutant with crystallographic 222 symmetry.
metal-organic compounds
The single-crystal X-ray structures of dimethyl 2,2′-bipyridine-6,6′-dicarboxylate, C14H12N2O4, and the copper(I) coordination complex bis(dimethyl 2,2′-bipyridine-6,6′-dicarboxylato-κ2N,N′)copper(I) tetrafluoroborate, [Cu(C14H12N2O4)2]BF4, are reported. The uncoordinated ligand crystallizes across an inversion centre and adopts the anticipated anti pyridyl arrangement with coplanar pyridyl rings. In contrast, upon coordination of copper(I), the ligand adopts an arrangement of pyridyl donors facilitating chelating metal coordination and an increased inter-pyridyl twisting within each ligand. The distortion of each ligand contrasts with comparable copper(I) complexes of unfunctionalized 2,2′-bipyridine.

Rat procathepsin B has been expressed in the yeast Pichia pastoris. The Cys29Ser mutant was incapable of self-processing. This mutant was crystallized in two forms, one diffracting to 2.8 Å resolution, the other to 3.5 Å resolution.

A model involving only a small number of parameters provides a convenient way of interpreting diffraction patterns from MCM-41 materials. Each parameter of the model has a clear physical meaning, and this approach is clearly superior to extracting pore structure information by fitting Gaussians to an observed diffraction pattern.
