| Atu2719 | metA | Atu2719 | Atu2718 | Aldose epimerase; Converts alpha-aldose to the beta-anomer. | Homoserine O-succinyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine. | 0.829 |
| cysD | hom | Atu1251 | Atu1588 | O-acetylhomoserine sulfhydrylase. | Homoserine dehydrogenase. | 0.893 |
| cysD | ilvA | Atu1251 | Atu1205 | O-acetylhomoserine sulfhydrylase. | Threonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA. | 0.810 |
