Sps_02405 | PFAM: Threonine synthase N terminus; Pyridoxal-phosphate dependent enzyme; TIGRFAM: threonine synthase. (426 aa) | ||||
ilvA | L-threonine ammonia-lyase; 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. (516 aa) | ||||
