  1. 1. Heme Protein Biogenesis - Catalase in Enterococcus faecalis

    Författare :Michael Baureder; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enterococcus faecalis; heme proteins; protein assembly; oxidative stress; catalase; cytochrome;

    Sammanfattning : Heme proteins form a large and diverse group of proteins which are involved in a variety of biological functions. The heme prosthetic group enables them to carry out redox reactions, transport electrons, bind gaseous molecules, and function as sensors. Despite their importance only little is generally known about heme protein biogenesis. LÄS MER

  3. 2. Mechanisms of alloxan diabetogenicity

    Författare :Kjell Grankvist; Inge-Bert Täljedal; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alloxan; catalase; experimental diabetes; free radicals; islets of Langerhans; rubidium accumulation; superoxide dismutase; Trypan Blue;

    Sammanfattning : Suspensions of pancreatic islet cells from ob/ob-mice were incubated with Trypan Blue. Microscope photometry showed that apparently viable cells excluded the dye completely, whereas the nuclei of non-viable cells accumulated Trypan Blue by a saturable process. LÄS MER
