2. 21. Ensemble methods for protein structure prediction

   Author : Marcin J. Skwark; Arne Elofsson; Michael Tress; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; model quality assessment; contact prediction; homology modeling; ab-initio prediction; consensus prediction; structural bioinformatics; bioinformatics; protein structure; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

   Abstract : Proteins play an essential role in virtually all of life's processes. Their function is tightly coupled to the three-dimensional structure they adopt.Solving protein structures experimentally is a complicated, time- and resource-consuming endeavor. READ MORE

4. 22. Transmembrane Proteins and Protein Structure Prediction : What we can learn from Computational Methods

   Author : John Lamb; Arne Elofsson; Paolo Marcatili; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; contact prediction; transmembrane protein; topology prediction; machine learning; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

   Abstract : A protein’s 3D-structure is essential to understand how proteins function and interact and how biochemical processes proceed in organic life. Despite the advancement in experimental methods, it remains expensive and time-consuming to determine protein structure experimentally. READ MORE

5. 23. Protein-surfactant interactions

   Author : Ank Valstar; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

   Abstract : Protein-surfactant interactions in aqueous media have been investigated. The globular proteins lysozyme and bovine serum albumin (BSA) served as model proteins. Several ionic and non-ionic surfactants were used.Fluorescence probe measurements showed that at low sodium dodecyl sulfate (SDS) concentration (< 0. READ MORE

6. 24. Membrane protein topogenesis

   Author : Karin Öjemalm; Gunnar von Heijne; Tracy Palmer; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; biokemi;

   Abstract : The membranes of cells are highly complex and heterogeneous structures that fulfill multiple vital tasks. They form thin barriers that seal out the environment, thus defining the cell’s boundaries. READ MORE

7. 25. Computational Protein Evolution : Modeling the Selectivity and Promiscuity of Engineered Enzymes

   Author : Klaudia Szeler; Shina C. Lynn Kamerlin; Mikael Widersten; Maria Ramos; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; enzymes; kinetics; catalysis; density functional theory; empirical valence bond; diesters; evolution; promiscuity; Biokemi; Biochemistry;

   Abstract : Enzymes are biological catalysts that significantly increase the rate of all biochemical reactions that take place within cells and are essential to maintain life. Many questions regarding their function remain unknown. READ MORE
