tRNA-guanine Transglycosylase (TGT) labeled with 5-fluorotryptophan in co-crystallized complex with 6-amino-2-(methylamino)-4-(4-(trifluoromethyl)phenethyl)-3,7-dihydro-8H-imidazo[4,5-g]quinazolin-8-one
Structural highlights
FunctionTGT_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] See Also
