The Number of Extreme Pathways Associated with the Production of the Indicated Amino Acid that Do Not Use the Indicated Carbon and Nitrogen Substrate
| Amino acid produced | EPs without alanine input | EPs without arginine input |
| Asparagine | 0 | 103 (30.3%) |
| Aspartate | 0 | 155 (31.6%) |
| Cysteine | 0 | 248 (24.3%) |
| Glutamine | 1 (0.3%) | 75 (23.8%) |
| Glutamate | 1 (0.2%) | 140 (28.4%) |
| Glycine | 0 | 130 (34.5%) |
| Lysine | 0 | 152 (24.9%) |
| Proline | 11 (1.3%) | 0 |
| Serine | 0 | 103 (29.0%) |
| Threonine | 0 | 115 (24.5%) |
| Tryptophan | 0 | 534 (27.3%) |
| Tyrosine | 0 | 248 (24.6%) |
[i] These calculations are performed under case 4 conditions. The percentages are based on the total number of extreme pathways for the production of an individual amino acid. EPs indicates extreme pathways.
