CC Note=Binds 2 [4Fe-4S] clusters per monomer. {ECO:0000255|HAMAP-
CC Rule:MF_00916};
CC -!- PATHWAY: tRNA modification; tRNA-queuosine biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_00916}.
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00916}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00916}.
