c3870 | cysE | c3870 | c4429 | L-serine dehydratase 1; Escherichia coli K-12 ortholog: b1814; Escherichia coli O157:H7 ortholog: z4464; Belongs to the iron-sulfur dependent L-serine dehydratase family. | Serine acetyltransferase; Escherichia coli K-12 ortholog: b3607; Escherichia coli O157:H7 ortholog: z5034; Belongs to the transferase hexapeptide repeat family. | 0.905 |
c3870 | glyA | c3870 | c3073 | L-serine dehydratase 1; Escherichia coli K-12 ortholog: b1814; Escherichia coli O157:H7 ortholog: z4464; Belongs to the iron-sulfur dependent L-serine dehydratase family. | 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. | 0.938 |

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. | 0.912 |
