功能
Catalytic subunit of the queuine tRNA-ribosyltransferase (TGT) that catalyzes the base-exchange of a guanine (G) residue with queuine (Q) at position 34 (anticodon wobble position) in tRNAs with GU (N) anticodons (tRNA-Asp , -Asn , -His and -Tyr) , resulting in the hypermodified nucleoside queuosine (7- ( ( (4 ,5-cis-dihydroxy-2-cyclopenten-1-yl) amino) methyl) -7-deazaguanosine) . Catalysis occurs through a double-displacement mechanism. The nucleophile active site attacks the C1' of nucleotide 34 to detach the guanine base from the RNA , forming a covalent enzyme-RNA intermediate. The proton acceptor active site deprotonates the incoming queuine , allowing a nucleophilic attack on the C1' of the ribose to form the product (By similarity) .
