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). Catalysis occurs
CC through a double-displacement mechanism. The nucleophile active site
CC attacks the C1' of nucleotide 34 to detach the guanine base from the
CC RNA, forming a covalent enzyme-RNA intermediate. The proton acceptor
CC active site deprotonates the incoming queuine, allowing a nucleophilic
CC attack on the C1' of the ribose to form the product.
CC {ECO:0000256|HAMAP-Rule:MF_03218}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=guanosine(34) in tRNA + queuine = guanine + queuosine(34) in
CC tRNA; Xref=Rhea:RHEA:16633, Rhea:RHEA-COMP:10341, Rhea:RHEA-

CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03218};
CC -!- SUBUNIT: Heterodimer of a catalytic subunit and an accessory subunit.
CC {ECO:0000256|HAMAP-Rule:MF_03218}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03218}.
CC -!- SIMILARITY: Belongs to the queuine tRNA-ribosyltransferase family.
