  2. 6. The specificities of plant enzymes and their effects on the seed oil quality

    Author : Simon Jeppsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Triacylglycerols, glycerides with three fatty acids, are the chemical constituent of seed oils. The fatty acid composition determines the chemical and physical characteristics of an oil. Conventional vegetable oils contain a few reoccurring fatty acids, but plants can produce several hundreds of different fatty acids. READ MORE

  4. 7. The Structure-Function Relationship and Evolution of Deoxyribonucleoside Kinases

    Author : Zeeshan Mutahir; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The synthesis of deoxyribonucleoside triphosphates (dNTPs), building blocks of DNA, can be achieved by two different pathways in the cell. One is called de novo synthesis and the other is known as salvage pathway. The de novo pathway involves synthesis of dNTPs by utilizing basic molecules like sugars, amino acids, CO2, NH3, etc. READ MORE

    Abstract : The biological functions of proteins depend on their physical interactions with other molecules, such as proteins and peptides. Therefore, modeling the protein-ligand interactions is important for understanding protein functions in different biological processes. READ MORE

  6. 9. Cleavage Specificity of Mast Cell Chymases

    Author : Mattias K. Andersson; Lars Hellman; Gunnar Pejler; Per Venge; Uppsala universitet; []
    Keywords : Biology; Immunology; Mast cell; Serine protease; Chymase; Cleavage specificity; Phage display; Biologi;

    Abstract : Mast cells (MC) are potent inflammatory cells that are known primarily for their prominent role in IgE mediated allergies. However, they also provide beneficial functions to the host, e.g. in bacterial and parasitic defence. READ MORE

  7. 10. UDP-sugar metabolizing pyrophosphorylases in plants : formation of precursors for essential glycosylation-reactions

    Author : Daniel Decker; Leszek A. Kleczkowski; Henrik Vibe Schelle; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical library screening; Cell wall synthesis; Glycosylation; Nucleotide sugars; Oligomerization; Protein structure; Reverse chemical genetics; Sugar activation; UDP-sugar synthesis; biokemisk farmakologi; biochemical pharmacology; biokemi; Biochemistry; biology; biologi; molekylärbiologi; Molecular Biology;

    Abstract : UDP-sugar metabolizing pyrophosphorylases provide the primary mechanism for de novo synthesis of UDP-sugars, which can then be used for myriads of glycosyltranferase reactions, producing cell wall carbohydrates, sucrose, glycoproteins and glycolipids, as well as many other glycosylated compounds. The pyrophosphorylases can be divided into three families: UDP-Glc pyrophosphorylase (UGPase), UDP-sugar pyrophosphorylase (USPase) and UDP-N-acety lglucosamine pyrophosphorylase (UAGPase), which can be discriminated both by differences in accepted substrate range and amino acid sequences.
