RL Submitted (APR-2007) to the EMBL/GenBank/DDBJ databases.
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:0000255|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:0000255|HAMAP-Rule:MF_01446};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01446};
CC Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01446};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01446}.
CC -!- SIMILARITY: Belongs to the KAE1 / TsaD family. {ECO:0000255|HAMAP-
CC Rule:MF_01446}.
