Proteins performing a foreign‐gene‐silencing function analogous to that associated with H‐NS seem to be restricted to bacteria and to fall into four classes: H‐NS itself, Rok, MvaT, and Lsr2. In contrast, other types of NAP are widely distributed among prokaryotes. When a bacterium possesses one type of xenogeneic silencer, it typically will not also have an example of a different type, indicating specialisation between each protein type and its genome (Perez‐Rueda and Ibarra 2015).
