  1. 1. Regulation of Glutamine Synthetase in the Diazotroph Rhodospirillum rubrum

    Författare :Anders Jonsson; Stefan Nordlund; Karl Forchhammer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glutamine synthetase; Rhodospirillum rubrum; GlnE; PII; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : The bacterial cell needs ammonia for synthesis of glutamine from glutamate. Only one enzyme is able to catalyze this reaction, namely glutamine synthetase (GS). GS can be regulated both transcriptionally and post-translationally and it is present in all kingdoms of life. LÄS MER

  3. 2. Molecular aspects of glutathione synthetase deficiency

    Författare :Runa Vidar Njålsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Glutathione synthetase; kinetics; cooperativity; substrate affinity; splice mutations; phenotype; genotype;

    Sammanfattning : The tripeptide glutathione (GSH) is involved in several crucial pathways in the cell, for instance regulation of enzyme activity, DNA synthesis, and free radical scavenging. Synthesis of GSH takes place via two steps in the gamma-glutamyl cycle. LÄS MER

  4. 3. Molecular genetic studies of three autosomal recessive disorders : Sjögren-Larsson syndrome, glutathione synthetase deficiency and congenital ichthyosis

    Författare :Maritta Pigg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Sjögren-Larsson syndrome; glutathione synthetase deficiency; congenital ichthyosis; linkage analysis; allelic association; mutation analysis; transglutaminase 1 gene; Genetik; Clinical genetics; Klinisk genetik; Clinical Genetics; klinisk genetik;

    Sammanfattning : Investigations at the DNA level were performed in order to characterise the molecular basis forthree genetic disorders:Sjögren-Larsson syndrome (SLS) is characterised by congenital ichthyosis and severeneurological symptoms. Linkage analysis and allelic association of 24 Swedish families affectedby SLS showed linkage between the disease and the marker D17S805 on chromosome 17. LÄS MER

    Sammanfattning : Since the discovery of Mycobacterium tuberculosis (Mtb) as the bacterial agent causing tuberculosis, the permanent eradication of this disease has proven challenging. Although a number of drugs exist for the treatment of tuberculosis, 1.7 million people still die every year from this infection. LÄS MER
