O-sialoglycoprotein endopeptidase; 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 TsaE and TsaB. TsaD likely plays a direct catalytic role in this reaction; Belongs to the KAE1 / TsaD family.

N-acetylmuramoyl-L-alanine amidase.

tRNA delta(2)-isopentenylpyrophosphate transferase; Catalyzes the transfer of a dimethylallyl group onto the adenine at position 37 in tRNAs that read codons beginning with uridine, leading to the formation of N6-(dimethylallyl)adenosine (i(6)A); Belongs to the IPP transferase family.

DNA mismatch repair protein MutL; 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.

Protein of unknown function UPF0031; Catalyzes the dehydration of the S-form of NAD(P)HX at the expense of ADP, which is converted to AMP. Together with NAD(P)HX epimerase, which catalyzes the epimerization of the S-and R-forms, the enzyme allows the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration.

Translation factor SUA5; Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Catalyzes the conversion of L-threonine, HCO(3)(-)/CO(2) and ATP to give threonylcarbamoyl-AMP (TC-AMP) as the acyladenylate intermediate, with the release of diphosphate.

Alanine racemase; Catalyzes the interconversion of L-alanine and D-alanine. May also act on other amino acids; Belongs to the alanine racemase family.

Translation factor SUA5; Belongs to the SUA5 family.

GTP-binding protein, HSR1-related; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. HflX GTPase family.
