Arrangement of peptides/nickel transporter operons within the five strains of Faecalibacterium prausnitzii. Phylogenetic analysis of sequences associated with the nickel/peptides transporter complex revealed six distinct operons of potentially different origins. Operon constituents are coloured by KO (red = K02031; green = K02032; blue = K02033; orange = K02034; purple = K02035) with operon order according to numbering of genes in IMG chromosome maps.
