摘要：

Pseudomonas aeruginosa bacterioferritin, also known as cytochrome b1 or cytochrome b557, has been isolated with 9 haems per 24 subunits. Various forms of the protein have been prepared including the completely haem-free protein and the fully haem-loaded protein with 24 haems per 24 subunits. The presence of the core does not significantly affect haem addition or removal. The absorbance ratio of the non-haem-iron-loaded protein, 278 nm:417 nm (oxidised), can be used to estimate the haem loading. © 1990.
