WebAug 1, 2010 · The Ftn and Bfr proteins exhibit many similarities and have the same biological purpose — iron storage. Dps proteins are more distinct and normally function in iron detoxification as opposed to storage. The Ftn proteins are the archetypical members of the Ferritin family. They are found in all three domains of life. WebApr 1, 2024 · Bacteria possess two ferritin-like iron storage proteins, the bacterial ferritin (FtnA) and bacterioferritin (Bfr) as recently reviewed [27]. In Pseudomonas aeruginosa under iron-limiting conditions, cytosolic BfrB binds to the bacterioferritin-associated ferredoxin (Bfd) and accepts electrons from its [2Fe–2S] cluster, causing Fe 3+ stored ...
