2.4.2.64	guanine34 in tRNA + queuine	-	Drosophila melanogaster	queuine34 in tRNA + guanine	-	?
2.4.2.64	guanine34 in tRNA + queuine	the enzyme replaces a guanine in the anticodon of tRNAs for Asn, Asp, His, and Tyr. In the absence of queuine, this enzyme catalyzes an exchange between free guanine with guanine	Drosophila melanogaster	queuine34 in tRNA + guanine	-	?
