Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

Functioni

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).UniRule annotation

Catalytic activityi

Queuosine(34) in tRNA + acceptor + H2O = epoxyqueuosine(34) in tRNA + reduced acceptor.UniRule annotation

Pathwayi: tRNA-queuosine biosynthesis

This protein is involved in the pathway tRNA-queuosine biosynthesis, which is part of tRNA modification.UniRule annotation1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
