Fig. 2From: The fciTABC and feoABI systems contribute to ferric citrate acquisition in Stenotrophomonas maltophiliaComparison of the possible ferric citrate uptake systems among S. maltophilia, E. coli, and P. aeruginosa. A The genetic organizations of fecIRABCED operon of E. coli, fecIRA operon of P. aeruginosa, and their fecA homolog in S. maltophilia. Genes encoding for FecA are marked in green. The numbers labelled below the arrows indicate the protein identities and similarities compared to the S. maltophilia FecA protein. B The genetic organizations of fciTABC operon of S. maltophilia and its homologs in E. coli and P. aeruginosa. Genes encoding for FciA and its homologues are marked in green. The numbers labelled below the arrows indicate the protein identities and similarities compared to the S. maltophilia homologsBack to article page
