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:0000256|HAMAP-
CC Rule:MF_00916}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=AH2 + epoxyqueuosine(34) in tRNA = A + H2O + queuosine(34) in
CC tRNA; Xref=Rhea:RHEA:32159, Rhea:RHEA-COMP:18571, Rhea:RHEA-

CC ChEBI:CHEBI:194431, ChEBI:CHEBI:194443; EC=1.17.99.6;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00916};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00916};
CC Note=Binds 2 [4Fe-4S] clusters per monomer. {ECO:0000256|HAMAP-
CC Rule:MF_00916};
CC -!- COFACTOR:
CC Name=cob(II)alamin; Xref=ChEBI:CHEBI:16304;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00916};
CC -!- PATHWAY: tRNA modification; tRNA-queuosine biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_00916}.
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_00916}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00916}.
CC -!- SIMILARITY: Belongs to the QueG family. {ECO:0000256|HAMAP-
CC Rule:MF_00916}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00916}.
