Oxidation of actin methionine residues by the oxidation-reduction enzyme Mical is known to lead to actin filament depolymerization. SelR enzymes are now shown to reduce these oxidized actin methionines, revealing a regulated redox reaction mechanism through which cells control the assembly and disassembly of actin filaments.
