  1. 1. Structural Insights at Sub-Ångstrom, Medium and Low Resolution: Crystallization of Trypsin, Bacterioferritin, Photosynthetic Reaction Center, and Photosynthetic Core Complex

    Författare :Weixiao Yuan Wahlgren; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein crystallization; cubic phase; sponge phase; bicelle; trypsin; bacterioferritin; reaction center; core complex; photosynthesis;

    Sammanfattning : The catalytic action of serine proteases depends on the interplay of a nucleophile, a general base and a general acid. The catalytic triad is composed of serine, histidine and aspartate residues. The serine acts as a nucleophile while the histidine plays a dual role as the general base or acid at different steps of the reaction. LÄS MER

  2. 2. Protein stabilization. Some methods and mechanisms

    Detta är en avhandling från Department of Biotechnology, Lund University

    Sammanfattning : Popular Abstract in Swedish Proteiner är biologiska molekyler som kan utvinnas ur olika bakterier, svampar, djur och människor. I sin naturliga miljö bidrar de bl. a. till att katalysera (snabba på) olika kemiska reaktioner (enzymer), att sköta transporten av olika molekyler, bidra till immunförsvaret och tillväxtkontroll (hormoner).
