Abstract

Encapsulated ferritins (EncFtn) are a recently characterised member of the ferritin superfamily. EncFtn proteins are sequestered within encapsulin nanocompartments and form a unique biological iron storage system. Here, we use native mass spectrometry and hydrogen-deuterium exchange mass spectrometry to elucidate the metal-mediated assembly pathway of EncFtn.
