CC -!- FUNCTION: Required for the formation of a threonylcarbamoyl group on
CC adenosine at position 37 (t(6)A37) in mitochondrial tRNAs that read
CC codons beginning with adenine. Probably involved in the transfer of the
CC threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6
CC group of A37. Involved in mitochondrial genome maintenance (By
CC similarity). May have a role in embryonic development in plants.
CC {ECO:0000255|HAMAP-Rule:MF_03179}.
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_03179};
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03179};
CC Note=Binds 1 divalent metal cation per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_03179};
CC -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_03179}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_03179, ECO:0000269|PubMed:19694617}; Peripheral membrane
CC protein {ECO:0000269|PubMed:19694617}.
CC -!- TISSUE SPECIFICITY: Expressed in young developing leaves, roots,
CC flowers and siliques. {ECO:0000269|PubMed:19694617}.
CC -!- DEVELOPMENTAL STAGE: Expressed transiently at the early stages of
CC seedling development. Maximal expression is reached during week 3 after
CC seed germination. {ECO:0000269|PubMed:19694617}.
CC -!- DISRUPTION PHENOTYPE: Embryonic lethal. {ECO:0000269|PubMed:19694617}.
CC -!- SIMILARITY: Belongs to the KAE1 / TsaD family. {ECO:0000255|HAMAP-
CC Rule:MF_03179}.
