  1. 1. Combined structural methods to characterize an oligomeric small heat shock protein Hsp21

    Author : Gudrun Rutsdottir; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small heat shock proteins; chaperones; crosslinking mass spectrometry; Stable isotope labeling; quantification; small angle X-ray scattering; cryo-electron microscopy; combined structural methods; plant stress;

    Abstract : Small heat shock proteins (sHsps) are found in all organisms and evolved early in the history of life, prior to the divergence of the three domains of life (Archaea, Bacteria, and Eukarya). Their malfunction is connected to several different diseases in humans, such as Alzheimer’s and Parkinson’s disease. READ MORE

    Abstract : Thiopurine S-methyltransferase (TPMT) belongs to the Class I S-adenosylmethionine-dependent methyltransferase (SAM-MT) super family of structurally related proteins. Common to the members of this large protein family is the catalysis of methylation reactions using S-adenosylmethionine (SAM) as a methyl group donor, although SAM-MTs act on a wide range of different substrates and carry out numerous biologically important functions.

  3. 3. Exploring Unorthodox Aquaporins : Characterization of NbXIPs & AtNIPs

    Author : Henry Ampah-Korsah; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aquaporins; XIPs; NIPs; Phosphorylation; Pichia pastoris; Overexpression; boric acid; membrane proteins;

    Abstract : AbstractAquaporins are membrane integral proteins that facilitate the transport of waterand/or other small neutral molecules across biological membranes in cells in allforms of life. Among the subfamilies of aquaporins in higher plants, the X IntrinsicProteins (XIPs) are the most recently discovered subfamily and the leastcharacterized. READ MORE

  4. 4. Extending the Reach of Computational Approaches to Model Enzyme Catalysis

    Author : Beat Anton Amrein; Shina Caroline Lynn Kamerlin; Adrian Mulholland; Uppsala universitet; []

    Abstract : Recent years have seen tremendous developments in methods for computational modeling of (bio-) molecular systems. Ever larger reactive systems are being studied with high accuracy approaches, and high-level QM/MM calculations are being routinely performed. READ MORE

  5. 5. Input Estimation in Structural Dynamics

    Author : Lars Nordström; Chalmers University of Technology; []
    Keywords : sensitivity analysis; dynamic programming; input estimation; load identification; ill-posedness; regularization; indirect force measurement; inverse problems;

    Abstract : Knowledge of time-varying excitation is of importance in the design of a wide range of engineering applications, from spacecraft and processing plants to electronic circuits. Regardless of the actual application or underlying physics, the expected input will play a key role in the determination of adequate system properties and parameters. READ MORE
