Notes

[back to top]


Asn, Asp, Tyr, and His tRNA anticodons are modified. QueA converts 7-deazaguanine (preQ1-tRNA) to epoxyqueuosine (oQ-tRNA) in the penultimate step of Q-tRNA biosynthesis. The final step to make Q-tRNA from oQ-tRNA may be a cobamide-dependent reduction, but the gene is unknown (Frey, 1988). tgt mutants lack queuosine and are have reduced survival in stationary phase. (Noguchi, 1982).[1]
