Hfq RNA chaperone; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family.

Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.

DNA mismatch repair factor; This protein is involved in the repair of mismatches in DNA. It is required for dam-dependent methyl-directed DNA mismatch repair. May act as a 'molecular matchmaker', a protein that promotes the formation of a stable complex between two or more DNA-binding proteins in an ATP-dependent manner without itself being part of a final effector complex (By similarity). Overexpression of mutSL partially suppresses the high spontaneous mutation frequency of a ytkD/mutM/mutY triple disruption which lacks the system required to prevent damage by oxidized guanine (8-oxo [...]

tRNA N(6)-threonylcarbamoyladenosine (t(6)A) methylthiotransferase; Catalyzes the methylthiolation of N6- threonylcarbamoyladenosine (t(6)A), leading to the formation of 2- methylthio-N6-threonylcarbamoyladenosine (ms(2)t(6)A) at position 37 in tRNAs that read codons beginning with adenine. Belongs to the methylthiotransferase family. MtaB subfamily.

Pseudouridylate synthase I; Formation of pseudouridine at positions 38, 39 and 40 in the anticodon stem and loop of transfer RNAs.

phenylalanyl-tRNA synthetase (beta subunit); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.

Ribosome associating GTPase; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis.

tRNA(NNU) t(6)A37 threonylcarbamoyladenosine modification; Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Is involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaD and TsaB; this reaction does not require ATP in vitro. TsaE seems to play an indirect role in the t(6)A biosynthesis pathway, possibly in regulating the core enzymatic function of TsaD. Displays ATPase activity in vitro, which is modulated by the oligo [...]

Fused diaminohydroxyphosphoribosylaminopyrimidine deaminase; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
