We report the three-dimensional structure determined by high-pressure macromolecular crystallography (HPMX) of a 135-kDa homo-tetrameric enzyme, urate oxidase from Aspergillus flavus complexed with its potent inhibitor 8-azaxanthin. Urate oxidase crystals are quite sensitive to pressure, as three-dimensional order is lost

Crystallization and preliminary neutron diffraction measurements of rasburicase, a recombinant urate oxidase enzyme expressed by a genetically modified Saccharomyces cerevisiae strain, complexed with a purine-type inhibitor (8-azaxanthin) are reported. Neutron Laue diffraction data were collected to 2.1 A resolution using

Xanthine dehydrogenase (EC 1.2.1.37) activity was determined in the fat body of the Chagas' disease vector Triatoma infestans using a system in which phenazine methosulphate was associated with p-iodonitrotetrazolium violet as electron acceptors for the oxidation of the substrate xanthine.

Large amounts of data from high-throughput metabolomic experiments are commonly visualized using a principal component analysis (PCA) two-dimensional scores plot. The question of the similarity or difference between multiple metabolic states then becomes a question of the degree of overlap
