Fig. 6.

Sus operon structure across Bacteroides species. Selected sus operons from the type strains of several human gut Bacteroides species are displayed, identified via conservation of the operon structure surrounding a susG homolog. Numbers displayed above each gene indicate the percent identity of the encoded protein and in parentheses the percent coverage of the match to the homologous protein from B. thetaiotaomicron. For example, 63 % (100 %) above the susC homolog from B. ovatus indicates that the SusC homolog from B. ovatus is 63 % identical to the B. thetaiotaomicron SusC and that this match covers 100 % of the protein sequence
