Transposon mutagenesis and plasmid complementation studies have identified two genes, fepD and fepG, which are essential for ferrienterobactin transport in Escherichia coli. These genes mapped in the enterobactin gene cluster and genetic evidence indicated that they are transcribed as part of an operon (fepD, fepG, fepC). The nucleotide sequence of fepD was determine; it could encode a hydrophobic 33.8 kDa protein with sequence homologies to other iron and vitamin B12 transport proteins. Also identified, between fepD and fepB, was an open reading frame (ORF43) with no detectable function; its 43 kDa protein product (P43) was seen on polyacrylamide gels. The fepD-C operon and ORF43 were divergently transcribed from a 110bp region containing a binding site for the repressor protein Fur. << Less

Nucleotide sequence and genetic organization of the ferric enterobactin transport system: homology to other periplasmic binding protein-dependent systems in Escherichia coli.

The nucleotide sequence of the Escherichia coli fep genomic region has been determined. Three new loci were identified. One of these, P43, encodes a membrane protein that is not essential for ferric enterobactin transport. Two others, fepD and fepG, were found to be essential for transport and their translational products showed extensive homology to other integral membrane proteins involved in TonB-dependent transport processes. The FepC amino acid sequence suggested a peripheral membrane location and revealed conserved ATP-binding domains. Together these data indicate that ferric enterobactin is transported through a typical periplasmic binding protein-dependent system. In addition, the transcriptional organization of these genes was examined and primer extension analysis identified a single iron-regulated bidirectional promoter between the P43 gene and the fepDGC operon. << Less
