CC -!- FUNCTION: Component of the EKC/KEOPS complex that is required for the
CC formation of a threonylcarbamoyl group on adenosine at position 37
CC (t(6)A37) in tRNAs that read codons beginning with adenine. The complex
CC is probably involved in the transfer of the threonylcarbamoyl moiety of
CC threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37. KAE1 likely
CC plays a direct catalytic role in this reaction, but requires other
CC protein(s) of the complex to fulfill this activity. The EKC/KEOPS
CC complex also promotes both telomere uncapping and telomere elongation.
CC The complex is required for efficient recruitment of transcriptional
CC coactivators. {ECO:0000255|HAMAP-Rule:MF_03180}.
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_03180};
CC -!- COFACTOR:
CC Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03180};
CC Note=Binds 1 divalent metal cation per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_03180};
CC -!- SUBUNIT: Component of the EKC/KEOPS complex composed of at least BUD32,
CC CGI121, GON7, KAE1 and PCC1; the whole complex dimerizes.
CC {ECO:0000255|HAMAP-Rule:MF_03180}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03180}.
CC Nucleus {ECO:0000255|HAMAP-Rule:MF_03180}.
CC -!- SIMILARITY: Belongs to the KAE1 / TsaD family. {ECO:0000255|HAMAP-
CC Rule:MF_03180}.
