CC -!- FUNCTION: Catalyzes the attachment of threonine to tRNA(Thr) in a two-
CC step reaction: L-threonine is first activated by ATP to form Thr-AMP
CC and then transferred to the acceptor end of tRNA(Thr). Also edits
CC incorrectly charged L-seryl-tRNA(Thr). {ECO:0000255|HAMAP-
CC Rule:MF_00184}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-threonine + tRNA(Thr) = AMP + diphosphate + H(+) + L-
CC threonyl-tRNA(Thr); Xref=Rhea:RHEA:24624, Rhea:RHEA-COMP:9670,

CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00184};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00184};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00184}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00184}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC {ECO:0000255|HAMAP-Rule:MF_00184}.
