CC -!- FUNCTION: Non-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). {ECO:0000255|HAMAP-
CC Rule:MF_03043}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03043};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_03043};
CC -!- SUBUNIT: Heterodimer of a catalytic subunit and an accessory subunit.
CC {ECO:0000255|HAMAP-Rule:MF_03043}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03043}.
CC -!- SIMILARITY: Belongs to the queuine tRNA-ribosyltransferase family.
CC QTRT2 subfamily. {ECO:0000255|HAMAP-Rule:MF_03043}.
