| ahcY | hom | SRM1_05374 | SRM1_01082 | Adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine. | Homoserine dehydrogenase. | 0.961 |
| ahcY | ilvA_2 | SRM1_05374 | SRM1_05530 | Adenosylhomocysteinase; May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine. | L-threonine dehydratase biosynthetic IlvA; 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. | 0.957 |
