Chorismate mutase; KEGG: spq:SPAB_03380 6.0e-193 tyrA; bifunctional chorismate mutase/prephenate dehydrogenase; K04092 chorismate mutase K04517; Psort location: Cytoplasmic, score: 9.97; locus tag in AE006468 is STM2669; tyrA.

Anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).

Translation elongation factor G; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-G/EF-2 s [...]

KEGG: sty:STY1951 0. putative ATP-dependent helicase; K03722 ATP-dependent DNA helicase DinG; Psort location: Cytoplasmic, score: 8.96; locus tag in AE006468 is STM1821; yoaA.

Phosphate acetyltransferase; Involved in acetate metabolism. In the N-terminal section; belongs to the CobB/CobQ family.

Universal bacterial protein YeaZ; KEGG: ecp:ECP_1750 2.1e-103 protease YeaZ K01423; locus tag in AE006468 is STM1820; yeaZ.

Putative endoribonuclease L-PSP; Locus tag in AE006468 is STM4458; yjgF.

Ribonuclease PH; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.

Threonine ammonia-lyase; 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.
