1. 1. Characterization of ATP-dependent protein dynamics under native-like conditions

   Författare :Harsha Ravishankar; Magnus Andersson; Hans Wolf-Watz; Lise Arleth; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; structural dynamics; ATPases; MD simulations; X-ray scattering; FTIR spectroscopy; ATP; TR-XSS; structural biology.; Biochemistry; biokemi;

   Sammanfattning : Proteins are biological macromolecules capable of accelerating biochemical reactions. To accomplish this, proteins undergo changes in their molecular structure. Advances in structural biology have resulted in ever-increasing numbers of high-resolution protein structures. LÄS MER

3. 2. Calcium transporting ATPases in plant cells

   Författare :Malin Olbe; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Triticum aestivum; calcium; Brij 58; calmodulin; Ca2 signalling; inside-out; endoplasmic reticulum; plant; plasma membrane; proteolysis; P-type ATPase; spinach; Spinacea oleracea; trypsin; two-phase; wheat.; Plant biochemistry; Växtbiokemi;

   Sammanfattning : Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes.

   Sammanfattning : By cleaving peptide bonds, proteases either activate or degrade proteins and maintain protein quality control in response to various developmental stimuli and environmental factors. My work has focused on elucidating the role of the filamentation temperature sensitive protein H (FtsH) proteases. LÄS MER

7. 5. P-type ATPases studied by electron microscopy and two-dimensional crystallization

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

   Sammanfattning : 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. LÄS MER
