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 TsaE and TsaB. TsaD likely plays a direct catalytic role
CC in this reaction. {ECO:0000255|HAMAP-Rule:MF_01445}.
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:0000255|HAMAP-Rule:MF_01445};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01445};
CC Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01445};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01445}.
CC -!- SIMILARITY: Belongs to the KAE1 / TsaD family. {ECO:0000255|HAMAP-
CC Rule:MF_01445}.
