Crystallography of complexes
The CCP4 Study Weekend 2006 covered a wide range of topics associated with structural studies of complexes between proteins, proteins and nucleic acids and proteins and small molecules. The programme was composed of lectures from different areas of structural biology including: preparation and characterization of complexes for structural analysis, co-crystallization and soaking techniques, mole...
متن کاملRadiation damage to nucleoprotein complexes in macromolecular crystallography
Significant progress has been made in macromolecular crystallography over recent years in both the understanding and mitigation of X-ray induced radiation damage when collecting diffraction data from crystalline proteins. In contrast, despite the large field that is productively engaged in the study of radiation chemistry of nucleic acids, particularly of DNA, there are currently very few X-ray...
متن کاملsynthesis of binuclear platinum complexes containing biphosphine ligand
هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
Crystallography of molecular excited states . Transition - metal nitrosyl complexes and the study of transient species
The study of photoinduced processes in crystals is a frontier area of crystallographic research, which requires development of novel experimental and computational methods. In a series of studies, long-lived metastable states, generated upon photoirradiation of transition-metal nitrosyl complexes, have been identified as ç nitrosyl and isonitrosyl linkage isomers, and their detailed geometry ha...
متن کاملRole of X-Ray Crystallography in Structural Studies of Pyridyl-Ruthenium Complexes
It is extremely important for chemists to establish the structure of new compounds. A more accurate understanding of the structure leads to the construction of appropriate reaction systems. For example, although the well-known platinum complex, [PtCl2(NH3)2], has two geometrical isomers (cis and trans in Fig. 1), only the cis-isomer (so-called cisplatin) exhibits prominent antitumor activity (R...
