Crystallization (Commentary)

Crystallization (Comment) Organism
crystal structure of the enzyme in a complex with NAD(H), to 1.5 A resolution. The tetrameric enzyme assumes an unusual quaternary structure with the dinucleotides positioned quite closely to one another. Both 2-oxoglutarate and the UDP-linked sugar bind in the enzyme active site with their carbon atoms, C-2 and C-3', respectively, abutting the re face of the cofactor. They are positioned about 3 A from the nicotinamide C-4. The UDP-linked sugar substrate adopts a highly unusual curved conformation when bound in the enzyme's active site cleft Pseudomonas aeruginosa
crystal structures of the enzyme in a complex with NAD(H) and 2-oxoglutarate, and the enzyme in a complex with NAD(H) and its substrate UDP-N-acetyl-D-glucosaminuronic acid, to 1.45 A and 2.0 A resolution, respectively. The tetrameric enzyme assumes an unusual quaternary structure with the dinucleotides positioned quite closely to one another. Both 2-oxoglutarate and the UDP-linked sugar bind in the enzyme active site with their carbon atoms, C-2 and C-3', respectively, abutting the re face of the cofactor. They are positioned about 3 A from the nicotinamide C-4. The UDP-linked sugar substrate adopts a highly unusual curved conformation when bound in the enzyme's active site cleft. Residues Lys101 and His185 most likely play key roles in catalysis Thermus thermophilus
