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   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01852}.
CC   -!- SIMILARITY: Belongs to the SUA5 family. TsaC subfamily.
