  1. 6. Computational Studies of Enzymatic Enolization Reactions and Inhibitor Binding to a Malarial Protease

    Author : Isabella Feierberg; Modesto Orozco; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; enzyme mechanism; enolate; molecular dynamics; empirical valence bond; glyoxalase I; ketosteroid isomerase; triosephosphate isomerase; malaria; aspartic protease; plasmepsin; linear interaction energy; drug design; Teoretisk kemi; Theoretical chemistry; Teoretisk kemi; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Enolate formation by proton abstraction from an sp3-hybridized carbon atom situated next to a carbonyl or carboxylate group is an abundant process in nature. Since the corresponding nonenzymatic process in water is slow and unfavorable due to high intrinsic free energy barriers and high substrate pKa s, enzymes catalyzing such reaction steps must overcome both kinetic and thermodynamic obstacles.

  2. 7. Interaction Studies of Secreted Aspartic Proteases (Saps) from Candida albicans : Application for Drug Discovery

    Author : Dan Backman; Helena Danielson; Birgitta Tomkinson; Gunnar Henriksson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; SPR Biosensor; Secreted aspartic proteases; Candida albicans; interaction kinetics; drug discovery; protease inhibitor; Biokemi; Biochemistry; Biokemi;

    Abstract : This thesis is focused on enzymatic studies of the secreted aspartic proteases (Saps) from Candida albicans as a tool for discovery of anti-candida drugs. C. albicans causes infections in a number of different locations, which differ widely in the protein substrates available and pH. Since C. READ MORE

    Abstract : Today, the demand for speed in drug discovery is constantly increasing, particularly in the iterative processes of hit validation and expansion and lead optimization. Irradiation with microwaves (MWs) has been applied in the area of organic synthesis to accelerate chemical reactions and to facilitate the generation of new chemical entities since 1986. READ MORE

  4. 9. Lipid sponge phase nanostructures as carriers for enzymes

    Author : Maria Valldeperas Badell; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sponge phase; lipid liquid crystals; DGMO; GMO-50; polysorbate 80; encapsulation of proteins; Aspartic protease; β-galactosidase; X-ray and neutron scattering; Raman spectroscopy; adsorption; cryo-TEM;

    Abstract : Nonlamellar lipid liquid crystalline phases have many potential applications, such as for drug delivery, protein encapsulation or crystallization. Lipid liquid crystalline sponge phase (L3) has so far not been very much considered in these applications, in spite of apparent advantages in terms of its flexibility and capacity of forming large aqueous pores able to encapsulate large bioactive molecules.

  5. 10. Analyses of the expression and function of the aspartic protease napsin

    Author : Takayuki Ueno; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Two-dimensional gel electrophoresis (2 DE) is one of the powerful tools for the expression profiling of proteins. Using 2 DE, two polypeptides which are expressed exclusively in primary lung adenocarcinomas have been described. Mass spectrometry of tryptic digests of these proteins revealed that they were identical to napsin A. READ MORE
