CC -!- FUNCTION: Catalyzes the methylthiolation of N6-
CC threonylcarbamoyladenosine (t(6)A), leading to the formation of 2-
CC methylthio-N6-threonylcarbamoyladenosine (ms(2)t(6)A) at position 37 in
CC tRNAs that read codons beginning with adenine.
CC {ECO:0000250|UniProtKB:Q5VV42}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[sulfur carrier]-SH + AH2 + N(6)-L-
CC threonylcarbamoyladenosine(37) in tRNA + 2 S-adenosyl-L-methionine =
CC 2-methylsulfanyl-N(6)-L-threonylcarbamoyladenosine(37) in tRNA + 5'-
CC deoxyadenosine + [sulfur carrier]-H + A + 2 H(+) + L-methionine + S-
CC adenosyl-L-homocysteine; Xref=Rhea:RHEA:37075, Rhea:RHEA-COMP:10163,

CC Evidence={ECO:0000250|UniProtKB:Q5VV42};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00780};
CC Note=Binds 2 [4Fe-4S] clusters. One cluster is coordinated with 3
CC cysteines and an exchangeable S-adenosyl-L-methionine.
CC {ECO:0000255|PROSITE-ProRule:PRU00780};
CC -!- SIMILARITY: Belongs to the methylthiotransferase family. CDKAL1
CC subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAB89997.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
