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

    University dissertation from Stockholm : Institutionen för biokemi och biofysik

    Author : Anders Jonsson; Stockholms universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glutamine synthetase; Rhodospirillum rubrum; GlnE; PII; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

  3. 3. Design and Synthesis of Novel Glutamine Synthetase Inhibitors and Development of Palladium(0)-Catalyzed Aminocarbonylation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Abstract : Tuberculosis (TB) is a major infectious disease, killing about 2 million people annually throughout the world. Today's TB treatment is a lengthy procedure involving a combination of antibiotics. No new TB drug has been introduced onto the market in the past 40 years, and the emergence of multi- and extensively drug-resistant TB calls for new drugs. READ MORE

  4. 4. Salvage and de novo synthesis of nucleotides in Trypanosoma brucei and mammalian cells

    University dissertation from Umeå : Medicinsk kemi och biofysik

    Author : Artur Fijolek; Umeå universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nucleotides; ribonucleotide reductase; Ara-A; p53R2; Trypanosoma brucei; African sleeping sickness; trypanosomiasis; CTP synthetase; adenosine kinase; acivicin; adenine arabinoside; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi;

    Abstract : All living cells are dependent on nucleic acids for their survival. The genetic information stored in DNA is translated into functional proteins via a messenger molecule, the ribonucleic acid (RNA). Since DNA and RNA can be considered as polymers of nucleotides (NTPs), balanced pools of NTPs are crucial to nucleic acid synthesis and repair. READ MORE

  5. 5. Structural Studies of Glutamine Synthetases – Towards the Development of Novel Antitubercular Agents

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Wojciech W. Krajewski; Uppsala universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Biochemistry Structural biology; NATURVETENSKAP Kemi Biokemi Strukturbiologi;

    Abstract : Glutamine synthetase (GS) plays an important role in nitrogen metabolism, where it catalyzes the ATP-dependent condensation of glutamate and ammonia to yield glutamine. Recent studies showed the importance of M. tuberculosis GS (MtGS) for growth and survival of the bacterium, and demonstrated its potential as a drug target. READ MORE
