1. 1. Rational redesign of Candida antarctica lipase B

   Författare :Anders Magnusson; Karl Hult; Bernhard Hauer; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Candida antarctica lipase B; rational redesign; secondary alcohols; substrate-assisted catalysis; S-selective; entropy; aldolase; stereospecificity pocket; oxyanion hole.; Biokemi; Biochemistry; Biokemi;

   Sammanfattning : This thesis describes the use of rational redesign to modify the properties of the enzyme Candida antarctica lipase B. Through carefully selected single-point mutations, we were able to introduce substrate-assisted catalysis and to alter the reaction specificity. LÄS MER

3. 2. Lipase Specificity and Selectivity : Engineering, Kinetics and Applied Catalysis

   Författare :Mohamad Takwa; Karl Hult; Bernhard Hauer; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

   Sammanfattning : The specificity and selectivity of the enzyme Candida antarctica lipase B (CALB) were studiedfor several substrates and applications.With help of molecular modeling, the active site of CALB was redesigned for the ring openingpolymerization of D,D‐lactide. LÄS MER
