B. thetaiotaomicron l-fucose-utilization gene cluster. (A) ORFs and the site of Tn4351 insertion. The bacterial l-fucose metabolic pathway is shown. The product of an ORF terminating 177 bp upstream of fucR shows homology to the 30S ribosomal protein S16 from several species. Another ORF beginning 187 bp downstream of fucP shares homology with several RNA polymerase σ factors. The GenBank accession number for this 10671-bp locus is AF137263. (B) Amino acid sequence of FucR. The underlined region encompasses a helix–turn–helix DNA binding region conserved in GntR family members.
