The importance of iron in living systems can be traced to the many complexes within which it is found, its chemical mobility undergoing oxidation-reduction reactions, and abundance Earth's crust. Iron most abundant element, by mass, Earth, constituting about 80% inner outer cores Earth. molten core 8000 km diameter, solid 2400 diameter. fourth element It chemically functional component mononuclear complexes, dinuclear [2Fe-2S] [4Fe-4S] clusters, [Fe-Ni-S] protophorphyrin IX, other protein biochemistry. Metals such as nickel, cobalt, copper, manganese are present crust could principle function place iron, but they scarce plentiful because nuclear stability stellar fusion reactions. seems likely that planets, formed same processes would also foster evolution life similarly important on those planets

Glutathione-dependent catalysis is a metabolic adaptation to chemical challenges encountered by all life forms. In the course of evolution, nature optimized numerous mechanisms use glutathione as most versatile nucleophile for conversion plethora sulfur-, oxygen- or carbon-containing electrophilic substances.This comprehensive review summarizes fundamental principles and compares structures glutathione-dependent enzymes, including reductase, glutaredoxins, peroxidases, peroxiredoxins, glyoxalases 1 2, transferases MAPEG. Moreover, open mechanistic questions, evolutionary aspects physiological relevance are discussed each enzyme family.It surprising how little known about many often reaction geometries acid-base catalysts neglected, puzzles remain unsolved despite almost century research. On one hand, several families with non-related protein folds recognize moiety their substrates. other thioredoxin fold used catalysis. Ancient well recent structural changes this did not only significantly alter mechanism, but also resulted in completely different functions.Glutathione-dependent enzymes excellent study objects structure-function relationships molecular evolution. Notably, times systems biology, outcome models on metabolism redox regulation more than questionable long properties neither studied nor understood. Furthermore, presented could have implications drug development. This article part Special Issue entitled Cellular functions glutathione.

Nucleotides are required for a wide variety of biological processes and constantly synthesized de novo in all cells. When cells proliferate, increased nucleotide synthesis is necessary DNA replication RNA production to support protein at different stages the cell cycle, during which these events regulated multiple levels. Therefore precursor nucleotides also strongly Nucleotide an energy intensive process that uses metabolic pathways across compartments several sources carbon nitrogen.
