1. Crystallographic studies of transaldolase : implications for the enzymatic mechanism and the evolution of class I aldolases
Sammanfattning : Transaldolase catalyzes the reversible transfer of a dihydroxyacetone moiety from a ketose donor to an aldose acceptor by forming a Schiff-base intermediate between a Iysine residue and dihydroxyacetone. It belongs to the class I aldolase family. LÄS MER
2. Colon cancer specific cytochrome P450 2W1 : polymorphism, membrane topology and endogenous roles in development
Sammanfattning : Cytochrome P450 2W1 (CYP2W1) belongs to a family of drug metabolizing monooxygenases with an unidentified yet endogenous function. CYP2W1 expression pattern has characteristic features of oncofetal genes. Previous studies have shown significant levels of CYP2W1 protein in 30% of human colon cancers and in 50% of corresponding liver metastases. LÄS MER
3. Climate-friendly rice - characterisation of rice varieties associated with low-methane emissions and improved bioenergy properties
Sammanfattning : Paddy rice cultivation contributes to global warming by emitting methane into the atmosphere. The aims of the work presented in this thesis were to breed climatefriendly rice varieties, to increase rice straw utilisation to reduce the impact of rice cultivation on the environment. LÄS MER
4. High Frequency Model of Electrified Railway Propulsion System for EMC Analysis
Sammanfattning : A model of the electrified railway propulsion system working in a wide frequency range is studied in this thesis. The high frequency modeling is the first stage to study and predict the Electromagnetic compatibility (EMC) problems in the electrified railway propulsion system, which are safety and reliability issues of high concern. LÄS MER
5. Post-translational modifications of proteins in human breast cancer : proteomics studies of phosphorylation and nitration and implication of these PTMs in tumorigenesis
Sammanfattning : Breast cancer is the most common cancer in women. Even though improvements in diagnosis and treatment of breast cancer have been made, it is still the most common cause of cancer death in women. There is a great need to find biomarkers for early detection of the disease and novel drug targets to fight the cancer. LÄS MER
