RT   "Mechanism of N6-threonylcarbamoyladenosine (t(6)A) biosynthesis: isolation
RT   and characterization of the intermediate threonylcarbamoyl-AMP.";
RL   Biochemistry 51:8950-8963(2012).
CC   -!- FUNCTION: Required for the formation of a threonylcarbamoyl group on
CC       adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning
CC       with adenine. Is involved in the transfer of the threonylcarbamoyl
CC       moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37,
CC       together with TsaD and TsaB; this reaction does not require ATP in
CC       vitro. TsaE seems to play an indirect role in the t(6)A biosynthesis
CC       pathway, possibly in regulating the core enzymatic function of TsaD.
CC       Displays ATPase activity in vitro, which is modulated by the oligomeric
CC       status of the protein. {ECO:0000269|PubMed:19246765,
CC       ECO:0000269|PubMed:23072323}.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=62.1 uM for ATP {ECO:0000269|PubMed:19246765};
CC         Vmax=10.5 nmol/min/mg enzyme {ECO:0000269|PubMed:19246765};
CC         Note=Values are given for the monomeric form. The rate of ATP
CC         hydrolysis is about three times higher for the monomeric form as
CC         compared to the homooligomeric forms.;
CC   -!- SUBUNIT: Monomer, homodimer or homotetramer; in equilibrium. Low salt
CC       concentration favors oligomerization, while high salt concentration
CC       favors the monomeric form. {ECO:0000269|PubMed:19246765}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:19246765}.
CC       Note=Localized predominantly at the cell poles and at the periphery of
CC       the bacterium.
CC   -!- INDUCTION: Expressed at all stages of growth.
CC       {ECO:0000269|PubMed:19246765}.
CC   -!- DISRUPTION PHENOTYPE: Cells lacking this gene exhibit significantly
CC       reduced growth in rich and minimal medium.
CC       {ECO:0000269|PubMed:19246765}.
CC   -!- MISCELLANEOUS: The four proteins YwlC, TsaD, TsaB and TsaE are
CC       necessary and sufficient for tRNA(NNU) t(6)A37
CC       threonylcarbamoyladenosine biosynthesis in vitro in B.subtilis.
CC       {ECO:0000305|PubMed:23072323}.
CC   -!- SIMILARITY: Belongs to the TsaE family. {ECO:0000305}.
CC   -!- CAUTION: The well-known t(6)A modification appears to be a hydrolyzed
CC       artifact of natural cyclic t(6)A (ct(6)A) that occurs during the
CC       preparation and handling of tRNA in B.subtilis and many other species
CC       (PubMed:23242255). In these species, the t(6)A modification is
CC       processed further by dehydration into ct(6)A, a reaction catalyzed by
CC       TcdA. {ECO:0000305}.
