In Staphylococcus aureus B47 grown in iron-restricted medium, six new, iron-regulated proteins occurred in cytoplasmic membrane. Protein of 14kDa has bound two complexes of iron: Fe(III)-staphylobactin and Fe(III)-acinetoferrin. Complexes of Fe(III)-ferrichrome and Fe(III)-rhodotorulic acid were not bound to any of new membrane protein. Iron of Fe(III)-staphylobactin and Fe(III)-acinetoferrin complexes was transported into the cells.
