CC -!- FUNCTION: Catalyzes the methylthiolation of an aspartic acid residue of
CC ribosomal protein S12. {ECO:0000255|HAMAP-Rule:MF_01865}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[sulfur carrier]-SH + AH2 + L-aspartate(89)-[ribosomal protein
CC uS12]-hydrogen + 2 S-adenosyl-L-methionine = 3-methylsulfanyl-L-
CC aspartate(89)-[ribosomal protein uS12]-hydrogen + 5'-deoxyadenosine +
CC [sulfur carrier]-H + A + 2 H(+) + L-methionine + S-adenosyl-L-
CC homocysteine; Xref=Rhea:RHEA:37087, Rhea:RHEA-COMP:10460, Rhea:RHEA-

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01865};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01865};
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_01865};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01865}.
CC -!- SIMILARITY: Belongs to the methylthiotransferase family. RimO
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_01865}.
