The L. reuteri genome is enriched in genes involved in amino acid production and utilization, including catabolism of tryptophan. A Pathway schematic of bacterial and abbreviated mammalian tryptophan metabolism. Enzymes with genomic evidence in Lactobacillus isolate are boxed in orange (ArAT), blue (FldH), and yellow (AmiE). B Heatmap of bacterial tryptophan specific enzymes with genomic evidence in Lactobacillus isolates. Enzymes are listed along the left in corresponding colors to the pathway in A with isolates and representative strains of the same species along the top and warmer colors indicating increasing copy number. Gene count colored by class of each ArAT or FldH is graphed in C and D respectively
