Encapsulin

Summary

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]

PDBsumstructure summary

Encapsulins are also used in synthetic biology. They are hard to discover due to their similarity to phage proteins.[2]

Function edit

Encapsulins serve many physiological functions, including catalysis, mineral storage, response to oxidative stress and secondary metabolism. There are ferritin-like encapsulins as well.[2]
