| cysE | glyA | BL03268 | BL03991 | Serine acetyltransferase; Catalyzes the acetylation of serine by acetyl-CoA to produce O-acetylserine (OAS). | 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. | 0.617 |
| cysE | hom | BL03268 | BL02137 | Serine acetyltransferase; Catalyzes the acetylation of serine by acetyl-CoA to produce O-acetylserine (OAS). | Homoserine dehydrogenase. | 0.633 |
| cysE | ilvA | BL03268 | BL03302 | Serine acetyltransferase; Catalyzes the acetylation of serine by acetyl-CoA to produce O-acetylserine (OAS). | 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. | 0.563 |
