1. Crystallographic studies on porphyrin metallation by ferrochelatase
Sammanfattning : Ferrochelatase catalyses the terminal step in heme biosynthesis by inserting a ferrous ion into protoporphyrin IX. The reaction mechanism has in this thesis been studied by mainly crystallographic methods. LÄS MER
2. Structural and physicochemical studies on metal and porphyrin binding by the Bacillus subtilis ferrochelatase
Sammanfattning : The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. LÄS MER
3. Host-Guest Interactions for Structural Analysis of Organic Molecules : Development of new Tools for Stereochemical Characterization
Sammanfattning : The focus of this thesis is on the development of molecular tweezers as host-guest systems for stereochemical characterization of small organic molecules.There are two central problems to stereochemical characterization of small molecules. LÄS MER
4. Exploring Molecular Interactions : Synthesis and Studies of Clip-Shaped Molecular Hosts
Sammanfattning : Molecular recognition via noncovalent interactions plays a key role in many biological processes such as antigen-antibody interactions, protein folding, the bonding and catalytic transformation of substrates by enzymes, etc. Amongst these noncovalent interactions, electrostatic interactions, hydrogen bonding, π-π interactions, and metal-to-ligand bonding are the most prominent.

5. Molecular and morphological studies on non-healing venous leg ulcers
Sammanfattning : Chronic skin ulcers are a major health problem and an increasing burden on health care providers. These ulcers have various underlying causes, such as venous or arterial insufficiency, diabetes, or vasculitis. Non-healing venous leg ulcers represent a condition characterized by excessive inflammation and presence of bacteria. LÄS MER
