RT genomics.";
RL ACS Chem. Biol. 12:844-851(2017).
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, ECO:0000269|PubMed:28128549}.
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 Evidence={ECO:0000255|HAMAP-Rule:MF_02089,
CC ECO:0000305|PubMed:28128549};
CC -!- PATHWAY: tRNA modification; tRNA-queuosine biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_02089, ECO:0000305|PubMed:28128549}.
CC -!- SIMILARITY: Belongs to the QueH family. {ECO:0000255|HAMAP-
CC Rule:MF_02089, ECO:0000305}.
