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

2. Class I Ribonucleotide Reductases : overall activity regulation, oligomerization, and drug targeting
Abstract : Ribonucleotide reductase (RNR) is a key enzyme in the de novo biosynthesis and homeostatic maintenance of all four DNA building blocks by being able to make deoxyribonucleotides from the corresponding ribonucleotides. It is important for the cell to control the production of a balanced supply of the dNTPs to minimize misincorporations in DNA. READ MORE
