    Sammanfattning : Halogen bonding is a weak interaction. In this thesis the three center four electron halogen bond, [N−X−N]+, has been studied. The lighter halogens form highly unstable halonium ions that are reactive towards nucleophiles and their complexes were therefore investigated at low temperatures. LÄS MER

  2. 2. Structural analysis of microsomal glutathione transferase 1 by electron crystallography

    Författare :Ingeborg Schmidt-Krey; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : The goals of this project were the two-dimensional crystallization of the membrane protein microsomal glutathione transferase 1 and the three-dimensional structure determination by electron crystallography. Microsomal glutathione transferase 1 is a homotrimeric membrane protein. LÄS MER
