Function
function
Catalyzes 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
- epoxyqueuosine34 in tRNA + AH2 = queuosine34 in tRNA + A + H2O
Pathway
tRNA modification; tRNA-queuosine biosynthesis.
