The encapsulins are a family of bacterial proteins that serve as the main structural components of encapsulin nanocompartments.[1] There are several different encapsulin proteins, including EncA, which forms the shell, and EncB, EncC, and EncD, which form the core.[1]
Encapsulins are also used in synthetic biology. They are hard to discover due to their similarity to phage proteins.[2]
