  1. 1. Chiral recognition on cellulases : The active sites of the enzymes are involved

    Author : Hongbin Henriksson; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Two cellobiohydrolases (CBH I and CBH II) and endoglucanase I (EG I) fromTrichoderma reesei, and CBH 58 from Phanerochaete chrysosporium were immobilized onsilica as chiral stationary phases (CSPs) in HPLC for enantioseparation of a group ofpharmaceutical compounds. CBH I and CBH 58 wore excellent chiral selectors for β-adrenergic blocking agents, whereas CBH II displayed good enantioselectivity for someother compounds The CBHs share the common feature that their active sites are located intunnels.

  2. 2. Molecular Recognition Studies Based on Imprinting Technology

    Author : Cong Yu; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; imprinting; molecular recognition; polymer; chiral separation; acrylamide; chromatography; functional monomer; cross-linking; hydrogen bonding; hydrophobic interactions; aqueous media; solvent; antibody; mimics; receptor; artificial enzyme; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry;

    Abstract : In this thesis, I have focused on five main research areas: 1). A new type of imprinted polymer has been developed, namely the amide MIP. The amide functional monomers showed better hydrogen bonding capabilities in polar organic solvents and the resulting polymers exhibited good enantiomeric recognition properties in organic media.

    Abstract : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. READ MORE

  4. 4. Towards simulating fully charged protein-DNA systems in water : Zif268-DNA as a test case

    Author : Git Roxström; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; Molecular Dynamics simulation; Zif268; zinc fingers; GROMOS; linkers; recognition sites; Fysik; Physics; Fysik; Physical Chemistry; fysikalisk kemi;

    Abstract : In this thesis, we develop a computing strategy to simulate fully charged protein-DNA systems with a general force field (GROMOS87). The ions neutralizing the phosphates (P-ions) are submitted to global symmetry constraints. A model exhibiting ionic-atmosphere effects on mobile P-ions was implemented via very weak restraint forces. READ MORE

  5. 5. Learning Representations for Machine Activity Recognition

    Author : Kunru Chen; Thorsteinn Rögnvaldsson; Reza Akhavian; Högskolan i Halmstad; []

    Abstract : Machine activity recognition (MAR) is an essential and effective approach for equipment productivity monitoring. Developing MAR methods for forklift trucks, a vital piece of the industry, can benefit productivity efficiency, maintenance service, product design, and potential savings. READ MORE
