CC   -!- FUNCTION: Catalytic subunit of the queuine tRNA-ribosyltransferase
CC       (TGT) that catalyzes the base-exchange of a guanine (G) residue with
CC       queuine (Q) at position 34 (anticodon wobble position) in tRNAs with
CC       GU(N) anticodons (tRNA-Asp, -Asn, -His and -Tyr), resulting in the
CC       hypermodified nucleoside queuosine (7-(((4,5-cis-dihydroxy-2-
CC       cyclopenten-1-yl)amino)methyl)-7-deazaguanosine) (PubMed:11255023,
CC       PubMed:20354154). Catalysis occurs through a double-displacement
CC       mechanism. The nucleophile active site attacks the C1' of nucleotide 34
CC       to detach the guanine base from the RNA, forming a covalent enzyme-RNA
CC       intermediate. The proton acceptor active site deprotonates the incoming
CC       queuine, allowing a nucleophilic attack on the C1' of the ribose to
CC       form the product (By similarity). {ECO:0000250|UniProtKB:P28720,
