    Sammanfattning : The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. LÄS MER

  4. 18. Expression and purification of membrane proteins: Focus on the G-protein coupled receptor MC4r

    Författare :Viveka Dolby; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enzymology; Proteiner; enzymologi; Proteins; melanocortin 4 receptor; GPCR; purification; Expression; membrane proteins;

    Sammanfattning : Membrane proteins are crucial components of the cell and are involved in many biological processes. Recombinant overexpression systems together with different purification methods are necessary to obtain large amounts of purified receptor for biophysical and functional studies. LÄS MER

  5. 19. Selective protein functionalisation via enzymatic phosphocholination

    Författare :Philipp Ochtrop; Christian Hedberg; Tom Grossmann; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chemical biology; organic synthesis; site-selective protein labeling; PTM; phosphocholination; nucleotides; bioorthogonal chemistry; proteomics; IMPDH2;

    Sammanfattning : Proteins are the most abundant biomolecules within a cell and are involved in all biochemical cellular processes ultimately determining cellular function. Therefore, to develop a complete understanding of cellular processes, obtaining knowledge about protein function and interaction at a molecular level is critical. LÄS MER

  7. 20. Computational analyses of biological sequences -applications to antibody-based proteomics and gene family characterization

    Författare :Mats Lindskog; Mathias Uhlén; Fredrik Sterky; Andersson Björn; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antigen; antibodies; antibody-based proteomics; biocomputing; bioinformatics; Bioinformatics; Bioinformatik;

    Sammanfattning : Following the completion of the human genome sequence, post-genomic efforts have shifted the focus towards the analysis of the encoded proteome. Several different systematic proteomics approaches have emerged, for instance, antibody-based proteomics initiatives, where antibodies are used to functionally explore the human proteome. LÄS MER
