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