Hanke and Renate Scheibe * Plant cell microcompartments: a redox-signaling perspective Abstract: This review describes how transient protein- protein interactions can contribute to direct informa- tion flow between subsequent steps of metabolic and signaling pathways, focusing on the redox perspective. Posttranslational modifications are often the basis for the dynamic nature of such macromolecular aggregates, named microcompartments. The high cellular

Introduction Redox signals play a pivotal role in cellular physiology and pathology (Lin and Beal, 2006; D’Autréaux and Toledano, 2007; Murphy et al., 2011; Kaludercic et al., 2014). Redox sensitive GFP (roGFP) variants and circular permutated YFP (cpYFP) derivatives have been developed for ratiometric imaging of such signals. These fluorescent proteins have major advantages over conventional fluorescent redox dyes. First, they are genetically encoded and can thus be stably expressed in transgenic animals and targeted to the site of interest. Second, they provide

Introduction Bacteria have to cope in their natural environment or during bacterial infection in association with the host immune system to reactive oxygen species (ROS) that are known to cause an oxidative stress response and affect the reduced state of the cytoplasm. ROS are produced in microorganisms as the unavoidable consequence of the aerobic life, by incomplete reduction of molecular oxygen during respiration (Imlay, 2003, 2008, 2013). Beside ROS, bacteria have to cope with many other redox-active compounds, including antimicrobials, antibiotics and

emphasis on oxidative modification on cysteine of molecules involved in TCR signaling. A number of studies have shown that imbalance in redox homeostasis characterizes many immune-related diseases (Staal et al., 1992; Chrobot et al., 2000; Kovacic and Jacintho, 2001; Reyes et al., 2005; Hultqvist et al., 2009; Kesarwani et al., 2013; Padgett et al., 2013). Nevertheless, despite intensive investigations during the last decade, mechanistic insights of how oxidation regulates T-cell signaling have not yet been completely revealed. T-cell activation T cells are organized in

batteries [3] were extensively investigated and commercialized, while their demonstration for large-scale energy storage meets some challenges in terms of safety, reliability, cost, and environment friendliness. Compared with the conventional secondary batteries, redox flow batteries (RFBs) with virtues of security, high efficiency, long cycling life, low-cost and flexible design are emerging as an effective technique for large-scale energy storage [4]. Vanadium redox batteries (VRBs) were first proposed by Skyllas-Kazacos and co-workers [5]. Other RFBs such as iron

Introduction: the challenge – regulation in photosynthesizing chloroplasts Photosynthesis consists of a complex series of redox reactions. The balance between light harvesting, physicochemical energy conversion and metabolic consumption of chemical energy determines the redox state of participating reactions. Thus the redox milieu of chloroplasts rapidly changes in dependence on the photosynthetic state, which, in turn, depends on environmental conditions such as light intensity, temperature and CO 2 availability. Thereby the redox milieu provides important
