  1. 6. Targets and strategies for drug development against human African sleeping sickness

    Författare :Farahnaz Ranjbarian; Anders Hofer; Staffan G. Svärd; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; T. brucei thymidine kinase; T. brucei methylthioadenosine phosphorylase; FANA-A purine nucleoside analogues; essential oils;

    Sammanfattning : Trypanosoma brucei is a causative agent of African sleeping sickness. It is an extracellular parasite which circulates in the blood, lymph and eventually invades the central nervous system. LÄS MER

  3. 7. DNA precursor biosynthesis-allosteric regulation and medical applications

    Författare :Reza Rofougaran; Anders Hofer; Thomas Borén; Staffan Eriksson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; DNA biosynthesis; ribonucleotide reductase; allosteric regulation; Trypanosoma brucei; adenosine kinase; nucleoside analogs; mitochondrial DNA; TWINKLE; Biokemi; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Ribonucleotide reductase (RNR) is a key enzyme for de novo dNTP biosynthesis. We have studied nucleotide-dependent oligomerization of the allosterically regulated mammalian RNR using a mass spectrometry–related technique called Gas-phase Electrophoretic Mobility Macromolecule Analysis (GEMMA).

  4. 8. Targeting the nucleotide metabolism of the mammalian pathogen Trypanosoma brucei

    Författare :Munender Vodnala; Anders Hofer; Arne Holmgren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Trypanosoma brucei; adenosine kinase; thymidine kinase; methylthioadenosine phosphorylase; mouser ribonucleotide reductase; E. coli ribonucleotide reductase; RNR; Ara-A; F-Ara-A; dNTP; NTP; doexynucleotide metabolism; nucleosides; nucleoside kinases; allosteric regulation; biologisk kemi; biological chemistry;

    Sammanfattning : Trypanosoma brucei causes African sleeping sickness in humans and Nagana in cattle. There are no vaccines available against the disease and the current treatment is also not satisfactory because of inefficacy and numerous side effects of the used drugs.T. LÄS MER

  5. 9. Biophysical investigations of ribonucleotide reductase : Activation and inhibition mechanisms

    Författare :Maria Öhrström; Astrid Gräslund; Anders Hofer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; Molekylär biofysik; Biophysics; biofysik;

    Sammanfattning : Ribonucleotide reductase (RNR) is the enzyme responsible for de novo synthesis of deoxyribonucleotides, needed for both synthesis and repair of cellular DNA. The RNRs known so far are divided into three distinct classes; I, II and III. The conventional class I enzyme is composed of two separate subunits. LÄS MER
