1. 11. Health Effects of Foods Enriched with Cereal beta-Glucans from Cereals

   Författare :Maria Biörklund; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Näringslära; Nutrition; glucose; cholesterol; oats; barley;

   Sammanfattning : Since soluble fibre in the form of the cereal beta-glucans found in oats and barley has been shown to have a positive effect on lipid and glucose metabolism, people at risk of developing cardiovascular diseases or diabetes might benefit from that a variety of palatable food products containing beta-glucans being available to them. The aim of the papers presented in the thesis was to evaluate the metabolic effects on persons with hypercholesterolemia or type 2 diabetes of various new food prototypes supplemented by beta-glucans.

3. 12. Ferrochelatase and Magnesiumchelatase: Metal chelation studied with mutants

   Författare :Ulf Olsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; chlorophyll; heme; barley; mutants; Magnesium chelatase; ferrochelatase; Metabolism; Biokemi; metabolism;

   Sammanfattning : Magnesium chelatase and ferrochelatase are two very important enzymes, which are involved in chlorophyll and heme biosynthesis, respectively. They both use protoporphyrin IX as substrate but magnesium chelatase inserts a magnesium ion whereas ferrochelatase inserts a ferrous ion. These two enzymes have been studied in this thesis. LÄS MER

4. 13. Infection biology of the plant pathogenic fungus Bipolaris sorokiniana

   Författare :Dace Apoga; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microscopy; Hordeum vulgare; barley; virulence; prehelminthosporol; phytotoxins; proteins; adhesion; fimbriae; extracellular matrix; Helminthosporium sativum; Cochliobolus sativus; Plant pathogenic fungi; Bipolaris sorokiniana; two-dimensional gel electrophoresis; mass spectrometry; gas chromatography; Ecology; Ekologi;

   Sammanfattning : Bipolaris sorokiniana is a fungal pathogen causing severe disease mainly in wheat and barley worldwide. In this thesis two aspects of the infection process were investigated: the adhesion mechanism of the fungus and the role of the non-host specific phytotoxin prehelminthosporol (PHL) in the disease.

5. 14. Enzymatic metal-chelation by porphyrins

   Författare :Andreas Hansson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tetrapyrrole; Plant biochemistry; Växtbiokemi; MIDAS; metallation; magnesium chelatase; integrin; heme; ferrochelatase; chlorophyll; barley; AAA ; ATPase;

   Sammanfattning : 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. LÄS MER

7. 15. Protein complexes in chlorophyll biosynthetic enzymes

   Författare :Ragna Peterson Wulff; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; mass spectrometry; Rhodobacter capsulatus; barley; cyclase; magnesium chelatase; chlorophyll biosynthetic pathway; Protein complex;

   Sammanfattning : Proteins are found on the inside, in the membrane, on the surface and on the outside of cells. They form complicated structures and they interact with other molecules and proteins. LÄS MER
