Phosphoserine phosphatase SerB; Derived by automated computational analysis using gene prediction method: Protein Homology.

Decarboxylase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Diaminopimelate decarboxylase; Specifically catalyzes the decarboxylation of meso- diaminopimelate (meso-DAP) to L-lysine.

Catalyzes the transamination of D-amino acids and their alpha-keto acids; Derived by automated computational analysis using gene prediction method: Protein Homology.

PLP-dependent 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.

Cysteine synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.

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.

Catalyzes de novo synthesis of phosphatidylserine from CDP-diacylglycerol and L-serine which leads eventually to the production of phosphatidylethanolamine; bounds to the ribosome; Derived by automated computational analysis using gene prediction method: Protein Homology.
