1. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones
Sammanfattning : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.

2. Tripeptidyl-Peptidase II : Structure, Function and Gene Regulation
Sammanfattning : The protein degradation process is of vital importance for the cell to maintain cellular functions. An important enzyme in this process is the multimeric tripeptidyl-peptidase II (TPP II). It removes tripeptides from a free N-terminus of the substrates. LÄS MER
3. Violaxanthin De-epoxidase and the Xanthophyll Cycle
Sammanfattning : The xanthophyll cycle is a mechanism for short term adaptation of plants to varying light intensities. It involves a reversible conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin, upon high light intensities. LÄS MER
4. Regulation of the Epstein-Barr virus C promoter by the OriP-EBNA1 complex
Sammanfattning : Epstein-Barr Virus (EBV) is an exclusively human, lymphotropic herpes virus that infects more than 90% of the population worldwide. Primary infection usually occurs during the early years of life and does not result in any recognized disease. LÄS MER
5. The enzymatic machinery of leukotriene biosynthesis : Studies on ontogenic expression, interactions and function
Sammanfattning : Leukotrienes (LTs) are biologically active arachidonic acid (AA) derivatives generated by the 5-lipoxygenase (5-LO) pathway. They are produced by myeloid cells. 5-LO converts AA to LTA4 in cooperation with 5-LO activating protein (FLAP). LTA4 is converted to LTB4, by LTA4-hydrolase (LTA4H) or to LTC4 by LTC4-synthase (LTC4S). LÄS MER
