Organism
Psychrobacter arcticus (strain DSM 17307 / 273-4)
Status
Reviewed-Annotation score: 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).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
