  1. 6. Structural aspecs on compounds in the CsI-(Cd/Hg)I2 system

    Författare :Rune Sjövall; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tetrahedral distorsion; thermal decomposition; Biltz concept; structural relationships; hydrate; iodine; mercury; caesium; cadmium; coordination number modelling; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Structural investigations of compounds in the CsI-(Cd/Hg)I2 system have been performed by means of X-ray diffraction, thermogravimetric and calorimetric techniques. Crystals of the compounds studied were synthesized from aqueous solutions of CsI and CdI2/HgI2 by the slow evaporation of water. LÄS MER

    Sammanfattning : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. LÄS MER

  4. 8. Computational Modelling of Ligand Complexes with G-Protein Coupled Receptors, Ion Channels and Enzymes

    Författare :Lars Boukharta; Johan Åqvist; Christopher A. Reynolds; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; molecular dynamics; ligand binding; free energy perturbation; linear interaction energy; binding free energy; homology modelling; structure prediction; alanine scanning; site-directed mutagenesis; hERG; GPCR; neuropeptide Y; HIV-1 reverse transcriptase; integron integrase; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Accurate predictions of binding free energies from computer simulations are an invaluable resource for understanding biochemical processes and drug action. The primary aim of the work described in the thesis was to predict and understand ligand binding to several proteins of major pharmaceutical importance using computational methods. LÄS MER

  5. 9. Prokaryotic respiratory supercomplexes : Studies of interactions between complexes III and IV

    Författare :Olga Stah; Pia Ädelroth; Petra Hellwig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bioenergetics; membrane protein; bacterial respiration; electron transport chain; supercomplex; cytochrome c oxidase; membrane-anchored cytochrome c; cytochrome bc1 complex; electron transfer; proton transfer; time-resolved spectroscopy; apoptosis; biokemi; Biochemistry;

    Sammanfattning : Respiratory processes for cellular energy conversion are carried out by the membrane-associated enzymes of the electron transfer chain (ETC). In recent years there has been emerging data showing that the members of the ETC organize into higher-level assemblies called supercomplexes (SCs) whose functional relevance is not yet fully understood.
