| STM2196 | tdcB | STM2196 | STM3244 | Putative D-serine dehydratase; Similar to E. coli L-serine deaminase (AAC74884.1); Blastp hit to AAC74884.1 (454 aa), 48% identity in aa 1 - 452; Belongs to the iron-sulfur dependent L-serine dehydratase family. | 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. TdcB also dehydrates serine to yield pyruv [...] | 0.954 |
