Protein
Queuine tRNA-ribosyltransferase
Gene
tgt, SNSL254_A0451
Organism
Salmonella newport (strain SL254)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Exchanges the guanine residue with 7-aminomethyl-7-deazaguanine in tRNAs with GUN anticodons (tRNA-Asp, -Asn, -His and -Tyr). After this exchange, a cyclopentendiol moiety is attached to the 7-aminomethyl group of 7-deazaguanine, resulting in the hypermodified nucleoside queuosine (Q) (7-(((4,5-cis-dihydroxy-2-cyclopenten-1-yl)amino)methyl)-7-deazaguanosine) By similarity.UniRule annotation

Catalytic activityi

Guanine(34) in tRNA + queuine = queuosine(34) in tRNA + guanine.UniRule annotation
Guanine(34) in tRNA + 7-aminomethyl-7-carbaguanine = 7-aminomethyl-7-carbaguanine(34) in tRNA + guanine.UniRule annotation

Cofactori

Binds 1 zinc ion per subunit By similarity.UniRule annotation
