FUNCTIONCatalyzes the conversion of epoxyqueuosine (oQ) to queuosine (Q), which is a hypermodified base found in the wobble positions of tRNA(Asp), tRNA(Asn), tRNA(His) and tRNA(Tyr).
CATALYTIC ACTIVITY Reaction=AH2 + epoxyqueuosine(34) in tRNA = A + H2O + queuosine(34) in tRNA; Xref=Rhea:RHEA:32159, Rhea:RHEA-COMP:18571, Rhea:RHEA- COMP:18582, ChEBI:CHEBI:13193, ChEBI:CHEBI:15377, ChEBI:CHEBI:17499, ChEBI:CHEBI:194431, ChEBI:CHEBI:194443; EC=1.17.99.6;
PATHWAYtRNA modification; tRNA-queuosine biosynthesis.
SIMILARITYBelongs to the QueH family.
