| Abstract |
The 70-amino-acid-residue N-terminal sequence of the bacterioferritin (BFR) of Azotobacter vinelandii was determined and shown to be highly similar to the N-terminal sequences of the Escherichia coli and Nitrobacter winogradskyi bacterioferritins. Electrophoretic and immunological analyses further indicate that the bacterioferritins of E. coli, A. vinelandii and Pseudomonas aeruginosa are closely related. A novel, two-subunit assembly state that predominates over the 24-subunit form of BFR at low pH was demonstrated. The results indicate that the bacterioferritins form a family of proteins that are distinct from the ferritins of plants and animals. |
