AOT82_1482 | Homoserine dehydrogenase. (452 aa) | ||||
AOT82_1833 | Threonine synthase. (473 aa) | ||||
thrB | Hypothetical protein; Belongs to the pseudomonas-type ThrB family. (388 aa) | ||||
asd | Aspartate-semialdehyde dehydrogenase; Catalyzes the NADPH-dependent formation of L-aspartate- semialdehyde (L-ASA) by the reductive dephosphorylation of L-aspartyl- 4-phosphate; Belongs to the aspartate-semialdehyde dehydrogenase family. (377 aa) | ||||
AOT82_2778 | Aspartokinase; Belongs to the aspartokinase family. (428 aa) | ||||
AOT82_523 | Threonine synthase. (86 aa) | ||||
ilvA | Threonine deaminase; 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. (517 aa) |
