To improve cobalt-containing catalytic systems for synthesis of hydrocarbons from carbon monoxide and hydrogen (Fischer-Tropsch synthesis), supports based on ultradispersed alloys of aluminum with rare and rare-earth metals (G, Ce, Sm) were obtained and studied. The catalytic activity parameters of the new catalysts were determined. 相似文献

Crystals of phosphopantetheine adenylyltransferase (PPAT) from Mycobacterium tuberculosis in the apo form and in complexes with coenzyme A (PPAT/CoA) and dephosphocoenzyme A (PPAT/dPCoA) were grown in microgravity by the capillary counter-diffusion method. The structures of PPAT Mt in the apo form and in complexes with ligands were solved based on the X-ray diffraction data collected from the grown crystals. The crystal structures were refined at 1.76, 1.59, and 1.59 Å resolution to Rf factors of 0.175, 0.159, and 0.157 and Rfree of 0.224, 0.208, and 0.206 for PPAT, PPAT/CoA, and PPAT/dPCoA, respectively. The atomic coordinates of the structures were deposited in the Protein Data Bank (PDB ID: 3RFF, 3RHS, and 3RBA). In these structures, the ligand-binding sites were determined, the environment of these sites was characterized, and the conformational changes accompanying the ligand binding were analyzed. 相似文献

Crystals of phosphopantetheine adenylyltransferase from Mycobacterium tuberculosis, thymidine phosphorylase from Escherichia coli, carboxypeptidase T from Thermoactinomyces vulgaris and its mutant forms, and crystals of complexes of these proteins with functional ligands and inhibitors were grown by the
capillary counter-diffusion method in the Japanese Experimental Module Kibo on the International Space Station. The high-resolution
X-ray diffraction data sets suitable for the determination of high-resolution three-dimensional structures of these proteins
were collected from the grown crystals on the SPring-8 synchrotron radiation facility. The conditions of crystal growth for
the proteins and the data-collection statistics are reported. The crystals grown in microgravity diffracted to a higher resolution
than crystals of the same proteins grown on Earth. 相似文献
