  1. 16. Redox and epigenetic modulators regulate cardiac function and remodeling in health and disease

    Författare :Zaher ElBeck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oxidative species are a divergent group of cellular metabolites with a wide variety of functions. Together with reductants, they regulate almost all cellular functions, from mediating cellular communications to catalyzing a variety of biochemical reactions, and further to posttranslationally modifying proteins.

    Författare :Albert Davydov; Marc Fontecave; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik;

    Sammanfattning : Ribonucleotide reductase (RNR) catalyses the reduction of all four ribonucleotides to the corresponding deoxyribonucleotides that are used by the cells for DNA synthesis. The active enzyme from mouse, Mycobacterium tuberculosis (M. tuberculosis) and aerobically grown E. LÄS MER

  4. 18. Protein disulfide isomerase : function and mechanism in oxidative protein folding

    Författare :Ruoyu Xiao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Protein disulfide isomerase; endoplasmic reticulum; protein folding;

    Sammanfattning : The formation of native intramolecular disulfide bonds is critical for the folding and stability of many secreted proteins. This process involves oxidation of protein thiols to form disulfide bonds as well as rearrangement of any non-native disulfide bonds that might form. LÄS MER
