Figure 2From: Genetic analysis and morphological identification of pilus-like structures in members of the genus BifidobacteriumSchematic comparative representation of pilus-encoding loci of various bifidobacterial strains. Each arrow indicates an ORF, the size of which is proportional to the length of the arrow. Colouring of the arrows represents the different function of the gene as indicated indicated above each arrow. The amino acid identity of the relevant encoded proteins is indicated in percentages.Back to article page
