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         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}.
