The Linocin_M18 is found in eubacteria and archaea [1,2]. These proteins, referred to as encapsulins, form nanocompartments within the bacterium which contain ferritin-like proteins or peroxidases, enzymes involved in oxidative-stress response. These enzymes are targeted to the interior of encapsulins via unique C-terminal extensions [3].
