ilvA | sdaA | PFREUD_03750 | PFREUD_18570 | 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. | L-serine dehydratase (L-serine ammonia-lyase); L-Serine <=> Pyruvate + NH3 / alpha-Amino acid <=> 2-Oxo acid + NH3 L-Serine <=> 2-Aminoacrylate + H2O /; Belongs to the iron-sulfur dependent L-serine dehydratase family. | 0.952 |
