5.4.99.12	tRNA uridine38	tRNALeu3 contains uridine at position 38. Wild-typeTruA pseudouridylates uridines at all three positions (38, 39 and 40) with efficiencies (kcat/KM) differing by less than 10fold, while R58A is inactive toward all three uridines. When flexibility of the anticodon stem loop is increased by mutating the two G:C base pairs in the stem of the anticodon stem loop of tRNALeu3 into A:U pairs, the kcat/KM increased 2fold. When flexibility is decreased by base-pairing the target U38 of tRNALeu3 with A32 instead of with U32, the kcat/KM decreases 10fold	Escherichia coli	tRNA pseudouridine38	-	?	410406
