1. Herpes simplex ribonucleotide reductase
Abstract : In all bacterial, plant and animal cells, as well as in many viruses, genetic information resides in DNA (deoxyribonucleic acid). Replication of DNA is essential for proliferation, and DNA-containing viruses (such as herpesviruses) must carry out this process within the mammalian cells they infect. READ MORE

2. Ribonucleotide reductase and DNA damage
Abstract : A prerequisite for a multicellular organism to survive is the ability to correctly replicate and repair DNA while minimizing the number of heritable mutations. To achieve this, cells need a balanced supply of deoxyribonucleoside triphosphates (dNTPs), the precursors for DNA synthesis. READ MORE

3. High (valent) on O2 : Ribonucleotide Reductase and Methane Monooxygenase
Abstract : Macromolecular X-ray crystallography (MX) is a powerful method to investigate protein structures. However, proteins with redox-active centres and radicals are very susceptible to photoreduction. READ MORE

4. Glutathione reductase from erythrocytes : purification, characterization and identification of functional histidine and arginine residues of the enzyme
Abstract : This investigation aims at the development of a rapid, simple purification procedure for glutathione reductase and at an exploration of the chemical groups of the enzyme essential for activity.Glutathione reductase from porcine erythrocytes was purified to homogeneity by the use of affinity chromatography on 2’,5’ ADP-Sepharose 4B.

5. Nitric Oxide Reductase from Paracoccus denitrificans : A Proton Transfer Pathway from the “Wrong” Side
Abstract : Denitrification is an anaerobic process performed by several soil bacteria as an alternative to aerobic respiration. A key-step in denitrification (the N-N-bond is made) is catalyzed by nitric oxide reductase (NOR); 2NO + 2e- + 2H+ → N2O + H2O. READ MORE
