Ligands: CL, GOL, ITE, ZN NonStd Res: FTR Related: 6ygy Activity: tRNA-guanine(34) transglycosylase, with EC number 2.4.2.29 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [TGT_ZYMMO] Exchanges the guanine residue with 7-aminomethyl-7-deazaguanine in tRNAs with GU(N) 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).[HAMAP-Rule:MF_00168]
