Abstract
Redox reactions are of high fundamental and practical interest since they are involved in both normal physiology and the pathogenesis of various diseases. However, this area of research has always been a relatively problematic field in the context of analytical approaches, mostly because of the unstable nature of the compounds that are measured. Genetically encoded sensors allow for the registration of highly reactive molecules in real-time mode and, therefore, they began a new era in redox biology. Their strongest points manifest most brightly in in vivo experiments and pave the way for the non-invasive investigation of biochemical pathways that proceed in organisms from different systematic groups. In the first part of the review, we briefly describe the redox sensors that were used in vivo as well as summarize the model systems to which they were applied. Next, we thoroughly discuss the biological results obtained in these studies in regard to animals, plants, as well as unicellular eukaryotes and prokaryotes. We hope that this work reflects the amazing power of this technology and can serve as a useful guide for biologists and chemists who work in the field of redox processes.

Abstract
Oxidative protein folding is mediated by a proteinaceous electron relay system, in which the concerted action of protein disulfide isomerase and Ero1 delivers the electrons from thiol groups to the final acceptor. Oxygen appears to be the final oxidant in aerobic living organisms, although the existence of alternative electron acceptors, e.g. fumarate or nitrate, cannot be excluded. Whilst the protein components of the system are well-known, less attention has been turned to the role of low molecular weight electron carriers in the process. The function of ascorbate, tocopherol and vitamin K has been raised recently. In vitro and in vivo evidence suggests that these redox-active compounds can contribute to the functioning of oxidative folding. This review focuses on the participation of small molecular weight redox compounds in oxidative protein folding.

Abstract
Thiol oxidants are expected to have multiple effects in living cells. Hence, mutations giving resistance to such agents are likely to reveal important targets and/or mechanisms influencing the cellular capacity to withstand thiol oxidation. A screen for mutants resistant to the thiol-specific oxidant dipyridyl disulfide (DPS) yielded tao3-516, which is impaired in the function of the RAM signaling network protein Tao3/Pag1p. We suggest that the DPS-resistance of the tao3-516 mutant might be due to deficient cell-cycle-regulated production of the chitinase Cts1p, which functions in post-mitotic cell separation and depends on Tao3p and the RAM network for regulated expression. Consistent with this, deletion of other RAM genes or CTS1 also resulted in increased resistance to DPS. Exposure to DPS caused extensive depolarization of the actin cytoskeleton. We found that tao3-516 is resistant to latrunculin, a specific inhibitor of actin polymerization, and that ram, Deltaace2, and Deltacts1 mutants are resistant to benomyl, a microtubule-destabilizing drug. Since septum build-up depends on the organization of cytoskeletal proteins, the resistance to cytoskeletal stress of Cts1p-deficient mutants might relate to bypass for abnormal septum-associated protein sorting. The broad resistance toward oxidants (DPS, diamide and H(2)O(2)) of the Deltacts1 strain links cell wall function to the resistance to oxidative stress and suggests the existence of targets that are common for these oxidants.

Abstract
Resistance to thiol oxidation can arise from mutations altering redox homeostasis. A Saccharomyces cerevisiae sit4-110 mutant is here described, which was isolated as resistant to the thiol-specific oxidant dipyridyl disulfide (DPS) and which contains a single-residue substitution in the SIT4 gene. Sit4p is a protein phosphatase with multiple roles in signal transduction through the target-of-rapamycin (TOR) pathway. We found that sit4-110 elevates the levels of glutathione. However, this cannot be the (only) cause for the DPS-resistance, since sit4-110 also conferred DPS/H2O2-resistance in a glutathione-deficient strain. Of the known Sit4p substrates, only Tip41p is involved in DPS-resistance; both Delta tip41 deletion and overexpression of the Tip41p target Tap42p resulted in increased DPS-resistance. Thus, the role of Sit4p in DPS-tolerance differs from its role during TOR-inactivation and salt stress. In view of Tap42p's known involvement in actin homeostasis, sit4-110 could compensate for putative actin-related defects caused by DPS. However, sit4-110 has pronounced actin polarization defects under both absence and presence of DPS. A relation between actin homeostasis and DPS resistance of sit4-110 cannot be ruled out, but our results suggest that unknown pathways might be involved in DPS resistance through mechanisms involving the Sit4p and/or Tap42p function(s).
