| ilvA | ilvB | AFE_0722 | AFE_0745 | 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. | Acetolactate synthase, large subunit, biosynthetic type; Identified by match to protein family HMM PF00205; match to protein family HMM PF02775; match to protein family HMM PF02776; match to protein family HMM TIGR00118. | 0.982 |
