1. 11. Quantum chemical modeling of enzymatic reactions : applications to the tautomerase superfamily

   Författare :Robin Sevastik; Fahmi Himo; Margaretha Blomberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioengineering; Bioteknik;

   Sammanfattning : In this thesis, quantum chemical methods are used to investigate enzymatic reaction mechanisms. The Density functional theory, in particular the hybrid B3LYP functional, is used to model two enzymes belonging to the tautomerase superfamily; 4-Oxalocrotonate Tautomerase (4-OT) and cis-Chloroacrylic Acid Dehalogenase (cis-CAAD).
