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. Catalyzes the conversion of L-threonine, HCO(3)(-)/CO(2)
CC and ATP to give threonylcarbamoyl-AMP (TC-AMP) as the acyladenylate
CC intermediate, with the release of diphosphate. {ECO:0000255|HAMAP-
CC Rule:MF_01852}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + hydrogencarbonate + L-threonine = diphosphate + H2O + L-
CC threonylcarbamoyladenylate; Xref=Rhea:RHEA:36407, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:17544, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:57926, ChEBI:CHEBI:73682; EC=2.7.7.87;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01852};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01852}.
CC -!- SIMILARITY: Belongs to the SUA5 family. TsaC subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01852}.
