CC -!- FUNCTION: Catalyzes the conversion of epoxyqueuosine (oQ) to queuosine
CC (Q), which is a hypermodified base found in the wobble positions of
CC tRNA(Asp), tRNA(Asn), tRNA(His) and tRNA(Tyr). {ECO:0000255|HAMAP-
CC Rule:MF_00916}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=AH2 + epoxyqueuosine(34) in tRNA = A + H2O + queuosine(34) in

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}.
