CC -!- FUNCTION: Catalyzes the methylthiolation of N6-(dimethylallyl)adenosine
CC (i(6)A), leading to the formation of 2-methylthio-N6-
CC (dimethylallyl)adenosine (ms(2)i(6)A) at position 37 in tRNAs that read
CC codons beginning with uridine. {ECO:0000255|HAMAP-Rule:MF_01864}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[sulfur carrier]-SH + AH2 + N(6)-dimethylallyladenosine(37) in
CC tRNA + 2 S-adenosyl-L-methionine = 2-methylsulfanyl-N(6)-
CC dimethylallyladenosine(37) in tRNA + 5'-deoxyadenosine + [sulfur
CC carrier]-H + A + 2 H(+) + L-methionine + S-adenosyl-L-homocysteine;

CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01864};
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|HAMAP-Rule:MF_01864};
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01864}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01864}.
CC -!- SIMILARITY: Belongs to the methylthiotransferase family. MiaB
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01864}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAP43997.1; Type=Erroneous initiation; Evidence={ECO:0000305};
