PSEEN2008 | glyA-1 | PSEEN2008 | PSEEN0806 | Putative L-serine dehydratase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; enzyme. | Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism. | 0.905 |

PSEEN2008 | ilvA-1 | PSEEN2008 | PSEEN2960 | Putative L-serine dehydratase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; enzyme. | Threonine dehydratase biosynthetic (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. | 0.919 |
