Fig. 6: Bioinformatic analysis of the B. breve lw01 genome and its Bsh gene.

A Circle map of the B. breve lw01 genome: genome sequence (ring 1), coding DNA sequences on the positive and negative strands (rings 2 and 3), RNA genes, ncRNA regions, CRISPR, Ori C (ring 4), GC content (ring 5), and GC skew (ring 6) are shown. B KEGG annotation and enrichment analysis. C GO annotation and enrichment analysis. D Schematic of the Bsh sequence construction and location. E Neighbour-joining phylogenetic tree of all genes annotated as bile salt hydrolase (choloylglycine hydrolase)-encoding genes (Bsh) in the Bifidobacterium species recorded in the NCBI database. F Predicted structures of B. breve lw01 BSH (upper panel) and consensus phylotype 4 BSH (lower panel). G Amino acid alignment of B. breve lw01 BSH and phylotype 4 BSH; the headers in grey represent the spatial variation per column, and the coloured boxes represent the structural similarity between regions.
