Fig 4. A conserved NH2-terminal motif in C7D2 transporters from CD related microbiomes.

(A) Alignment of NH2-terminal motifs from H11G11 and C7D2 transporters. NH2 terminal motifs were extracted from Expresso (3D Coffee) alignment performed from H11G11 and C7D2 transporters sequences presented Fig 1. * CD unrelated healthy subjects with C7D2 transporter, † no ORF predicted. Black squares indicate C7D2 transporter from CD related microbiomes. Spanish subjects are underlined. (B) Phylogenetic tree based on an alignment restricted to the “FGDFGND” NH2-terminal motif. Neighbor-Joining method was used to perform the tree. Sequences from F1S and C7D2 are absent because the first has no predicted ORF and the second has a truncated NH2-terminal sequence. (C) Proposed pattern for a beta-glucuronidase linked transporter specific of CD related microbiomes. The conserved pattern was determined using C7D2 transporter sequences from CD related microbiomes and published genomes (carrying GND-end motif) as found by the pattern discovery tool PRATT (http://www.expasy.ch/tools/pratt/).
