  2. 1. P-type ATPases studied by electron microscopy and two-dimensional crystallization

    Author : Kenneth Yijing Xian; Karolinska Institutet; Karolinska Institutet; []
    Keywords : electron microscopy; ion transport; membrane protein; P-type ATPase; two-dimensional crystallization;

    Abstract : Electron microscopy and two-dimensional crystallography have been used to study the molecular structures of the porcine renal Na+,K+-ATPase and the porcine gastric H+,K+-ATPase. In addition, morphological changes have been observed with electron cryomicroscopy from tubulovesicles in porcine gastric mucosae. READ MORE

  4. 2. Electron crystallography of soluble proteins

    Author : Matthew James Ellis; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Interfacial crystallization; electron microscopy; image processing; soluble protein; phospholipid layer;

    Abstract : Protein structures at moderate to high resolution can now be readily solved using an electron microscope and image processing techniques. The averaging conditions required to overcome the low signal to noise ratio of electron microscope images are particularly well satisfied by two-dimensional crystals. READ MORE

  5. 3. Structural studies of membrane proteins using transmission electron microscopy

    Author : Qie Kuang; Hans Hebert; Catherine Vénien-Bryan; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Membrane proteins play important roles for living cells. They control transportation of ions, solutes, and nutrients across the membrane and catalyze metabolic reactions. Transmission electron microscopy has its advantages in convenient sample preparation, straightforward structural determination, and wide applications for diverse specimens. READ MORE

  6. 4. New Fullerene Materials Obtained in Solution and by High Pressure High Temperature Treatment

    Author : Alexandr Talyzin; B. Sundqvist; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; fullerene; solution; high pressure; Raman spectroscopy; polymerisation; XRD; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Crystallization of C60 and C70 from organic solution often leads to the formation of new solvates and other fullerene compounds. In the present thesis, a number of such solvates were obtained and their phase transitions studied using in situ "in solution" techniques. READ MORE

  7. 5. Structural analysis of microsomal glutathione transferase 1 by electron crystallography

    Author : Ingeborg Schmidt-Krey; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The goals of this project were the two-dimensional crystallization of the membrane protein microsomal glutathione transferase 1 and the three-dimensional structure determination by electron crystallography. Microsomal glutathione transferase 1 is a homotrimeric membrane protein. READ MORE
