<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t6A37) in tRNAs that read codons beginning with adenine. Is probably 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. May also be involved in the metabolism of glycated proteins, but does not show sialoglycoprotease activity against glycophorin A.3 Publications

Miscellaneous

TsaBCDE are necessary and sufficient for tRNA(NNU) t6A37 threonylcarbamoyladenosine modification in vitro in E.coli.1 Publication

Caution

Was proposed to be a ligase for bicarbonate and threonine (PubMed:21285948): in the first step, TsaD would catalyze transfer of a gamma-phosphate group from ATP to bicarbonate, yielding carboxyphosphate and ADP; carboxyphosphate would then react with the threonine amine, producing N-carbamoylthreonine and phosphate. However, the protein ortholog in B.subtilis was shown to be involved in another step of t6A37 biosynthesis, i.e. the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaE and TsaB (PubMed:23072323). The protein ortholog in yeast (QRI7) was also shown to catalyze this step, and does not require the presence of additional proteins (PubMed:23620299).1 Publication
The well-known t6A modification appears to be a hydrolyzed artifact of natural cyclic t6A (ct6A) that occurs during the preparation and handling of tRNA in E.coli and many other species (PubMed:23242255). In these species, the t6A modification is processed further by dehydration into ct6A, a reaction catalyzed by TcdA.Curated

Appears essential for growth, since no null mutants can be obtained. Conditional depletion of this gene prevents t6A37 modification, and leads to pleiotropic phenotypes including increased or reduced cell size, unusual distribution of DNA around the cell periphery, nucleoid loss, and membrane/cell envelope defects. These phenotypes could be indirect effects of severe translation defects. The TsaD depletion phenotype is suppressed by overexpressing the response regulator RstA.4 Publications
