  1. 1. The birth of the hydrogenase : Studying the mechanism of [FeFe] hydrogenase maturation

    Författare :Brigitta Németh; Gustav Berggren; Ann Magnuson; Mohamed Atta; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HydF; HydA; [FeFe] hydrogenase maturation; semi-synthetic enzymes; Biokemi; Biochemistry;

    Sammanfattning : The [FeFe] hydrogenases are ancient metalloenzymes that catalyse the reversible interconversion between protons, electrons and molecular hydrogen. Despite the large structural variability within the [FeFe] hydrogenase family, the active site, the so called “H-cluster” is present in every representative.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; [FeFe] hydrogenases; hydrogen; catalysis; photocatalysis; spectroscopy; whole-cell; semi-artificial enzymes; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Sammanfattning : [FeFe] hydrogenases rare Nature’s best H2-processing catalysts, and one of the best candidates to satisfy societal need for cheap and efficient catalyst for H2-evolution. These enzymes owe their remarkable catalytic activities to their organometallic active site, called “H-cluster”. LÄS MER

  4. 3. Expression and synthetic activation of [FeFe]-hydrogenases in cyanobacteria

    Författare :Adam Wegelius; Peter Lindblad; Karin Stensjö; Namita Khanna; Matthew Posewitz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry with specialization in Microbial Chemistry; Kemi med inriktning mot mikrobiell kemi;

    Sammanfattning : Photosynthetic microbes can be utilized for hydrogen production, generating a clean, carbon neutral energy carrier from abundant substrates. Cyanobacteria are photosynthetic prokaryotes with large potential for biotechnological energy applications and several strains are capable of hydrogen production. LÄS MER
