Bacterioferritin
Bacterioferritin (Bfr) is an oligomeric
Bfr from Pseudomonas aeruginosa (PaBfr), unlike other Bfrs, is found to contain two subunit types, which differ considerably in their amino acid sequences. A similar hetero-assembly is seen in the ferritins of higher eukaryotes.
Bfr from Escherichia coli (EcBfr) which naturally shows structural instability and an incomplete self-assembly behavior by populating two oligomerization states has been used as a model for studies on the self-assembly of minimal protein nano-cages. [1]
