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
- AH2 + epoxyqueuosine34 in tRNA = A + H2O + queuosine34 in tRNA
Cofactor
Protein has several cofactor binding sites:
Note: Binds 2 [4Fe-4S] clusters per monomer.
Pathway
tRNA modification; tRNA-queuosine biosynthesis.
