J. Syst. Evol. Microbiol. 0:0-0(2020). 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 probably involved in the transfer of the CC threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 CC group of A37. {ECO:0000256|HAMAP-Rule:MF_01446}. CC -!- CATALYTIC ACTIVITY: CC Reaction=adenosine(37) in tRNA + L-threonylcarbamoyladenylate = AMP + CC H(+) + N(6)-L-threonylcarbamoyladenosine(37) in tRNA; CC Xref=Rhea:RHEA:37059, Rhea:RHEA-COMP:10162, Rhea:RHEA-COMP:10163, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:73682, ChEBI:CHEBI:74411, CC ChEBI:CHEBI:74418, ChEBI:CHEBI:456215; EC=2.3.1.234; CC Evidence={ECO:0000256|ARBA:ARBA00001866, ECO:0000256|HAMAP- CC Rule:MF_01446}; CC -!- COFACTOR: CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01446}; CC Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01446}; CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01446}. CC -!- SIMILARITY: Belongs to the KAE1 / TsaD family. {ECO:0000256|HAMAP- CC Rule:MF_01446}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01446}.
