  5. 14. The Beauty of the Bitter Devils : A Theoretical Study on Phosphate Molecules

    Författare :Maria Rudbeck; Andreas Barth; Margareta Blomberg; Leif Eriksson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik; Phosphate;

    Sammanfattning : Phosphate transfer reactions are catalyzed by a large number of enzymes comprising kinases, mutases and phosphatases. These enzymes play a fundamental role in controlling numerous life processes and it is therefore important to understand the origin of their potent catalytic power. An example is the Ca2+-ATPase.
