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:0000256|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 + 2 H(+) + L-
CC methionine; Xref=Rhea:RHEA:32155, Rhea:RHEA-COMP:10342, Rhea:RHEA-
