1. Exploring the Interplay of Lipids and Membrane Proteins
Sammanfattning : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. LÄS MER
2. Intracellular vesicles induced by monotopic membrane protein in Escherichia coli
Sammanfattning : The monotopic membrane protein alMGS, a glycosyltransferase catalyzing glucolipid synthesis in Acholeplasma laidlawii, was overexpressed in Escherichia coli. Optimization of basic growth parameters was performed, and a novel method for detergent and buffer screening using a small size-exclusion chromatography was developed. LÄS MER
3. Property-controlling Enzymes at the Membrane Interface
Sammanfattning : Monotopic proteins represent a specialized group of membrane proteins in that they are engaged in biochemical events taking place at the membrane interface. In particular, the monotopic lipid-synthesizing enzymes are able to synthesize amphiphilic lipid products by catalyzing two biochemically distinct molecules (substrates) at the membrane interface.

4. Membrane Stress and the Role of GYF Domain Proteins
Sammanfattning : Intracellular membrane trafficking is regulated by a large number of protein complexes and lipids. Blocking of trafficking disrupts normal membrane dynamics and causes membrane stress. LÄS MER
5. The advantages of being small : Glycosyltransferases in many dimensions and glycolipid synthesis in Mycoplasma Pneumoniae
Sammanfattning : The synthesis and breakdown of sugars is one of the most important functions in Nature. Consequently, sugar structures are used both as energy storage and as building blocks to stabilise and protect the cell. The formation of these structures is performed by glycosyltransferases (GT), an enzyme group structurally conserved within all kingdoms. LÄS MER
