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:0000256|ARBA:ARBA00002399}.
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'-
