tonB-independent ferrichrome-mediated iron transport in Escherichia coli spheroplasts.

PMCID: PMC294548  PMID: 6997278

Abstract

Although a functional tonB gene product was required for ferrichrome-mediated iron transport in whole cells of Escherichia coli K-12, such transport did not require the tonB+ function in spheroplasts. We suggest that in spheroplasts ferrichrome has direct access to the cytoplasmic membrane and that this is reflected in tonB-independent accumulation of ferrichrome iron. Therefore, the tonB gene product does not function in the translocation of ferrichrome iron across the inner membrane.
