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_02089}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=AH2 + epoxyqueuosine(34) in tRNA = A + H2O + queuosine(34) in
CC tRNA; Xref=Rhea:RHEA:32159, Rhea:RHEA-COMP:10345, Rhea:RHEA-
CC COMP:10346, ChEBI:CHEBI:13193, ChEBI:CHEBI:15377, ChEBI:CHEBI:17499,
CC ChEBI:CHEBI:82831, ChEBI:CHEBI:82834; EC=1.17.99.6;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_02089};
CC -!- PATHWAY: tRNA modification; tRNA-queuosine biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_02089, ECO:0000305|PubMed:28128549}.
CC -!- DISRUPTION PHENOTYPE: Queuosine is observed in queG or queH single
CC mutants, but queG-queH double mutants accumulate epoxyqueuosine and
CC lack queuosine. {ECO:0000269|PubMed:28128549}.
CC -!- SIMILARITY: Belongs to the QueH family. {ECO:0000255|HAMAP-
CC Rule:MF_02089, ECO:0000305}.
