This is the first serious attempt to synthesize all that became known of glutathione over the last three decades. The book contains an update of glutathione biosynthesis with special emphasis on its regulation in adaptive stress responses. Other chapters review glutathione transport systems and glutathione peroxidases and their differences in substrate specificities and localization. Further contributions center on the diversified roles of different glutathione-S-transferases and the roles of nitrosoglutathione and glutaredoxins - a subfamily of redoxins. The book closes with discussions of the analogous or homologous thiol metabolism in pathogens and the potential suitability of involved enzymes as drug targets.Key selling features: Summarizing the way glutathione is involved in stress responses Compiling the multiple ways glutathione affects inflammatory responses Disclosing how glutathione dampens programmed cell death such as ferroptosis Exploring the enigma of how enzymes accelerate glutathione-dependent processes Discussing how detoxification and redox regulation is mediated by glutathionylation Reviewing the ways glutaredoxins catalyze protein disulfide reduction Highlighting the medical impact of glutathione-related metabolic pathways Illustrating the role thiol metabolism of pathogens might play in drug discovery Chapter 11 of this book is freely available as a downloadable Open Access PDF at http://www.taylorfrancis.com under a Creative Commons Attribution (CC-BY) 4.0 license.

A volume within the Subcellular Biochemistry series is an appropriate setting for the first multi-author book devoted to the new family of antioxidant and cell signalling proteins, the peroxiredoxins. Within the antioxidant and cell signalling fields, even the existence of the peroxiredoxins has yet to be appreciated by many; with this book we aim to rectify this situation. We have tried to select diverse chapter topics to cover relevant aspects of the subject and to persuade knowledgeable authors to contribute a manuscript. As almost inevitable, a few authors let us down by failing to respond, others could not submit a manuscript in time for personal reasons. These unfortunately were two of the pioneers, Earl Stadtman and Sue Goo Rhee, but we appreciate that they communicated a lot of details that helped us to reconstruct the early phase of peroxiredoxin enzymology. We have thus compiled a book that competently covers the peroxiredoxin field from its beginnings through to currently relevant topics. In the introductory Chapter 1 we provide a short historical survey of the subject, based upon the early structural and enzymic studies on peroxiredoxins, and then lead into some of our current personal interests, such as the likely continuing contribution of transmission electron microscopy (TEM) for the study of high molecular mass peroxiredoxin complexes and the association of peroxiredoxins with other proteins, and the targeting of drugs against microbial peroxiredoxins, as future therapeutic approaches.
