Functional classification of the protein-coding sequences in three bacterial isolates. (A) The proportion of genomes identified for each COG (Clusters of Orthologous Genes) category. The value indicated represents the percentage of total gene numbers in each genome. (B) The number of genes matched to a CAZyme family responsible for xylan utilization. BP, Bifidobacterium pseudocatenulatum_BWX; BL, Bifidobacterium longum_BWX; MI, Megasphaera indica_BWX; CBM, carbohydrate-binding module; CE, carbohydrate esterase; GH, glycoside hydrolase; GT, glycosyl transferase; AA, auxiliary activity family.
