Abstract Oxidative stress represents a major challenge for cellular proteostasis. The accumulation of reactive oxygen species, such as hydrogen peroxide, impairs the fidelity of protein biosynthesis and causes non-specific oxidative protein modifications and aggregation. This situation is further aggravated by the oxidative stress-mediated drop in cellular ATP levels, which reduces the activity of ATP-dependent chaperones and proteases.
