  2. 16. Prediction of zinc-binding sites in proteins and efficient protein structure description and comparison

    Author : Nanjiang Shu; Sven Hovmöller; Elisabeth Sauer-Eriksson; Alexander Luybartsev; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc-binding; shape strings; protein structures; secondary structures; machine learning; Molecular biology; Molekylärbiologi; Biochemistry; Biokemi; Bioinformatics; Bioinformatik; Structural biology; Strukturbiologi; Biochemistry; biokemi; strukturbiologi; Structural Biology; Molecular Biology; molekylärbiologi;

    Abstract : A large number of proteins require certain metals to stabilize their structures or to function properly. About one third of all proteins in the Protein Data Bank (PDB) contain metals and it is estimated that approximately the same proportion of all proteins are metalloproteins. READ MORE

  4. 17. Structural Information and Hidden Markov Models for Biological Sequence Analysis

    Author : Jeanette Tångrot; Bo Kågström; Uwe H. Sauer; Erik Sonnhammer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HMM; structure alignment; protein structure; secondary structure; remote homologue; annotation; domain family; protein family; protein superfamily; protein fold recognition; Bioinformatics; Bioinformatik;

    Abstract : Bioinformatics is a fast-developing field, which makes use of computational methods to analyse and structure biological data. An important branch of bioinformatics is structure and function prediction of proteins, which is often based on finding relationships to already characterized proteins. READ MORE

  5. 18. Cotranslational protein biogenesis in Escherichia coli monitored by force profile analysis

    Author : Felix Nicolaus; Gunnar von Heijne; Ross Dalbey; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; cotranslational protein biogenesis; membrane protein; soluble protein; transmembrane helices; force profile analysis; arrest peptide; biokemi; Biochemistry;

    Abstract : Proteins are a diverse class of biomolecules that carry out many essential functions across all organisms. They can either be found in aqueous compartments or embedded in biological membranes of the cell and are called soluble or membrane proteins, respectively. READ MORE

  6. 19. Theoretical and Biochemical : Advancing Protein Structure Investigations with Complementing Computations

    Author : Maxim N. Brodmerkel; Erik G. Marklund; Carl Caleman; Charlotte Uetrecht; Helmut Grubmüller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics simulation; Protein structure; Structural biology; Protein hydration; Electric dipole; Collision Induced Unfolding;

    Abstract : Life as we know it today would not exist without proteins. The functions of proteins for us and other organisms are linked to their three-dimensional structures. As such, protein structure investigations are a crucial contribution for understanding proteins and the molecular basis of life. READ MORE

  7. 20. Quantum Chemical Interpretation of Protein Crystal Structure

    Author : Kristina Nilsson; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; structure; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi; protein; ComQum-X; Hess2FF; QM MM; hetero-compound; metal; oxidation state; protonation; force field; quantum refinement; refinement;

    Abstract : An initial model in the crystallographic structure determination process, usually contains many errors. To produce an accurate model, one must carry out several cycles of crystallographic refinement. READ MORE
