General annotation (Comments)

Function

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. HAMAP-Rule MF_00168

Catalytic activity

Guanine34 in tRNA + queuine = queuosine34 in tRNA + guanine. HAMAP-Rule MF_00168

Guanine34 in tRNA + 7-aminomethyl-7-carbaguanine = 7-aminomethyl-7-carbaguanine34 in tRNA + guanine. HAMAP-Rule MF_00168

Cofactor

Binds 1 zinc ion per subunit By similarity. HAMAP-Rule MF_00168

Pathway

tRNA modification; tRNA-queuosine biosynthesis. HAMAP-Rule MF_00168

Sequence similarities

Belongs to the queuine tRNA-ribosyltransferase family.
