1. 1. Catabolism of Pyrimidines in Yeast

   Författare :Anna Rasmussen; Molekylär cellbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pyrimidine degradation; catabolism of pyrimidines; nucleic acid precursors; yeast; Lachancea kluyveri; URC pathway;

   Sammanfattning : Pyrimidines are important precursors for nucleic acids, and constantly synthesized and degraded in the cell to maintain a balanced supply. Many microoganisms can also extract the nitrogens from the pyrimidine ring, and use them as a nitrogen source when “preferred” sources are absent. LÄS MER

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

   Författare :Artur Fijolek; Lars Thelander; Arne Holmgren; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nucleotides; ribonucleotide reductase; Ara-A; p53R2; Trypanosoma brucei; African sleeping sickness; trypanosomiasis; CTP synthetase; adenosine kinase; acivicin; adenine arabinoside; Biochemistry; Biokemi;

   Sammanfattning : 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. LÄS MER
