“…Recent studies of our group identified a novel small RNA‐binding protein, CcaF1, which is co‐expressed with four homologous CcsR sRNAs (CcsR1‐4) from a single promoter (Billenkamp et al, 2015; Grützner, Billenkamp, et al, 2021). While CcaF1 binds to various RNA targets (Grützner, et al, 2023; Grützner, Billenkamp, et al, 2021), affecting their stability and regulating gene expression, the CcsR sRNAs inhibit a glutathione‐dependent C1 metabolic pathway, leading to increased levels of antioxidative glutathione, which provides protection against reactive oxygen species and enhancing cell viability. Previous work documented a direct correlation between CcsR levels and stress resistance (Billenkamp et al, 2015; Grützner, Billenkamp, et al, 2021).…”
