The work presented in this thesis was carried out in the Membrane Enzy-mology group of the Groningen Biomolecular Sciences and Biotechnology Institute (GBB) at the University of Groningen and was financially sup-ported by the BE-Basic R&D Program, which was granted a FES subsidy from the Dutch Ministry of Economic affairs, agriculture and innovation (EL&I). The research was also funded by a NWO TOP-PUNT (project number 13.006) grant.
