| aldA | ilvA | HMPREF0621_0648 | HMPREF0621_0780 | Aldehyde dehydrogenase (NAD) family protein; COG: COG1012; Pfam: PF00171; InterPro: IPR015590; Belongs to the aldehyde dehydrogenase family. | Threonine ammonia-lyase, biosynthetic; 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. | 0.830 |
