CC   -!- FUNCTION: Transfers and isomerizes the ribose moiety from AdoMet to the
CC       7-aminomethyl group of 7-deazaguanine (preQ1-tRNA) to give
CC       epoxyqueuosine (oQ-tRNA). {ECO:0000255|HAMAP-Rule:MF_00113}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=7-aminomethyl-7-carbaguanosine(34) in tRNA + S-adenosyl-L-
CC         methionine = adenine + epoxyqueuosine(34) in tRNA + H(+) + L-
CC         methionine; Xref=Rhea:RHEA:32155, Rhea:RHEA-COMP:10342, Rhea:RHEA-

CC         EC=2.4.99.17; Evidence={ECO:0000255|HAMAP-Rule:MF_00113};
CC   -!- PATHWAY: tRNA modification; tRNA-queuosine biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00113}.
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00113}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00113}.
CC   -!- SIMILARITY: Belongs to the QueA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00113}.
