    Sammanfattning : Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial protein G (PGB1).

  4. 3. On electrostatic effects, minimal motion and other catalytic strategies used by enzymes

    Författare :Per-Olof Syrén; Karl Hult; Jiri Damborsky; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : Enzymes are powerful biocatalysts that provide rate accelerations of up to 1019 fold compared to the corresponding uncatalyzed reaction in solution. The origin of the remarkable performance displayed by enzymes has fascinated and puzzled researchers for over a hundred years. LÄS MER
