Figure 3.

Predicted amino acid metabolisms of T. whipplei based on the M. tuberculosis metabolisms described in KEGG. Metabolic pathways were predicted to be lost for nine amino acids (pink ovals). Additional deficiencies were predicted for other seven amino acids (blue ovals). Metabolic pathways for three amino acids (green ovals) were retained. Enzymes for the alanine (yellow oval) biosynthesis were not identified in both M. tuberculosis and T. whipplei. Enzymatic steps predicted to be present in both M. tuberculosis and T. whipplei are shown in black. Enzymatic steps present only in M. tuberculosis or in T. whipplei are shown in red and green, respectively. Enzymatic steps absent in both M. tuberculosis and T. whipplei are shown with dashed black lines.
