21. Mutational Analysis and Redesign of Alpha-class Glutathione Transferases for Enhanced Azathioprine Activity
Sammanfattning : Glutathione transferase (GST) A2-2 is the human enzyme most efficient in catalyzing azathioprine activation. Structure-function relationships were sought explaining the higher catalytic efficiency compared to other alpha class GSTs. LÄS MER
22. Expression and Mutagenesis studies of Candida antactica lipase B
Sammanfattning : Recombinant Candida antarctica lipase B was successfullyproduced in the methylotropic yeast Pichia pastoris. Thespecific activities of Candida antarctica lipase B produced inPichia pastoris and commercial Candida antarctica lipase B fromNovozymes were the same. In shake-flask cultivations theexpression levels were about 25 mg L-1. LÄS MER
23. The structural basis for the catalytic specificity of manganese lipoxygenases : 3D structure analysis of the lipoxygenase of Magnaporthe oryzae
Sammanfattning : Lipoxygenases (LOX) catalyze regio- and stereospecific oxygenation of polyunsaturated fatty acids to hydroperoxides. These hydroperoxides are further metabolized to leukotrienes and lipoxins in mammals, and are involved in asthma and inflammation. LOX of animals and plants contain iron as catalytic metal (FeLOX).

24. Functional Studies of the Neuropeptide Y System : Receptor-Ligand Interaction and Regulation of Food Intake
Sammanfattning : The members of the mammalian neuropeptide Y family, i.e. the peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP), are all involved in regulation of food intake. In human and most other mammals they act via receptors Y1, Y2, Y4 and Y5. LÄS MER
25. Leukotriene A4 hydrolase : studies of structure-function relationships by site-directed mutagenesis and X-ray crystallography
Sammanfattning : Inflammation is the pathophysiological mechanism by which an organism clears and rebuilds a site of infection or injury. It is also the characteristic feature of a multitude of severe diseases, with the potential of afflicting almost any organ system. LÄS MER
