D-tyrosyl-tRNA(Tyr) deacylase; An aminoacyl-tRNA editing enzyme that deacylates mischarged D-aminoacyl-tRNAs. Also deacylates mischarged glycyl-tRNA(Ala), protecting cells against glycine mischarging by AlaRS. Acts via tRNA- based rather than protein-based catalysis; rejects L-amino acids rather than detecting D-amino acids in the active site. By recycling D- aminoacyl-tRNA to D-amino acids and free tRNA molecules, this enzyme counteracts the toxicity associated with the formation of D-aminoacyl- tRNA entities in vivo and helps enforce protein L-homochirality. Belongs to the DTD family.

Acetyltransferase, GNAT family; Identified by similarity to GP:1652538; match to protein family HMM PF00583.

succinyl-CoA synthase, beta subunit; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The beta subunit provides nucleotide specificity of the enzyme and binds the substrate succinate, while the binding sites for coenzyme A and phosphate are found in the alpha subunit.

succinyl-CoA synthase, alpha subunit; Succinyl-CoA synthetase functions in the citric acid cycle (TCA), coupling the hydrolysis of succinyl-CoA to the synthesis of either ATP or GTP and thus represents the only step of substrate-level phosphorylation in the TCA. The alpha subunit of the enzyme binds the substrates coenzyme A and phosphate, while succinate binding and nucleotide specificity is provided by the beta subunit.

Conserved hypothetical protein TIGR00043; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3' terminus of the 16S rRNA.

Putative citrate lyase, beta subunit; Identified by similarity to SP:P77770; Belongs to the HpcH/HpaI aldolase family.

Ribosomal protein S17; One of the primary rRNA binding proteins, it binds specifically to the 5'-end of 16S ribosomal RNA.

TIM-barrel protein, yjbN family; Catalyzes the synthesis of 5,6-dihydrouridine (D), a modified base found in the D-loop of most tRNAs, via the reduction of the C5-C6 double bond in target uridines; Belongs to the Dus family. DusB subfamily.

DNA-binding protein Fis; Activates ribosomal RNA transcription. Plays a direct role in upstream activation of rRNA promoters; Belongs to the transcriptional regulatory Fis family.
