cysteine--tRNA ligase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class-I aminoacyl-tRNA synthetase family.

Bifunctional aspartate kinase/homoserine dehydrogenase I; Derived by automated computational analysis using gene prediction method: Protein Homology; In the C-terminal section; belongs to the homoserine dehydrogenase family.

Bifunctional indole-3-glycerol phosphate synthase/phosphoribosylanthranilate isomerase; Monomeric bifunctional protein; functions in tryptophan biosynthesis pathway; phosphoribosylanthranilate is rearranged to carboxyphenylaminodeoxyribulosephosphate which is then closed to form indole-3-glycerol phosphate; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the TrpC family.

Glycerol-3-phosphate dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the NAD-dependent glycerol-3-phosphate dehydrogenase family.

Threonine ammonia-lyase, biosynthetic; 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.

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

Peroxidase; 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.

Homoserine O-acetyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine.

UDP-3-O-(3-hydroxymyristoyl)glucosamine N-acyltransferase; Catalyzes the N-acylation of UDP-3-O-acylglucosamine using 3- hydroxyacyl-ACP as the acyl donor. Is involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell. Belongs to the transferase hexapeptide repeat family. LpxD subfamily.
