1. Prostasome Modulation of Blood Cascade System and Phosphoprotein Reactions with Focus on Prostate Cancer
Abstract : Prostasomes are extracellularly occurring submicron, membrane-surrounded organelles produced by the epithelial cells of the prostate and present in semen. Their precise physiological role is not known, although some of their properties assign them to important physiological and patho-physiological functions. READ MORE

2. The choreography of protein vibrations : Improved methods of observing and simulating the infrared absorption of proteins
Abstract : The work presented in this thesis has striven toward improving the capability to study proteins using infrared (IR) spectroscopy. This includes development of new and improved experimental and theoretical methods to selectively observe and simulate protein vibrations. READ MORE

3. Insights into structure and dynamics of the AAA+ motor of magnesium chelatase
Abstract : The insertion of Mg2+ into protoporphyrin IX represents the first committed step in the chlorophyll and bacteriochlorophyll biosynthetic pathways. The reaction is catalyzed by the multisubunit enzyme Mg-chelatase, which consists of three subunits, known as I (molecular weight ~40 kDa), D (~70 kDa), and H (~140 kDa). READ MORE

4. Magnesium Chelatase: Insights into the first Step of Chlorophyll Biosynthesis
Abstract : The enzyme magnesium chelatase inserts magnesium into protoporphyrin IX (Proto) to produce to magnesium protoporphyrin IX, the first unique intermediate of the chlorophyll biosynthetic pathway. Magnesium chelatase is composed of three distinct proteins termed I (molecular weight ~40 kDa), D (~70 kDa) and H (~140 kDa). READ MORE

5. Enzymatic metal-chelation by porphyrins
Abstract : This thesis deals with the structure and function of two different enzymes, ferrochelatase and magnesium chelatase, that catalyse similar reactions. When this work started, a three-dimensional model of ferrochelatase existed. Much was known about the enzyme, but some details remained unclear. READ MORE
