tRNA pseudouridine32 synthase (EC 5.4.99.28, RluA, pseudouridine synthase RluA, Pus9p, Rib2/Pus8p) is an enzyme with systematic name tRNA-uridine32 uracil mutase.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction

tRNA uridine32 tRNA pseudouridine32

The dual enzyme from Escherichia coli also catalyses the formation of pseudouridine746 in 23S rRNA.
