Accepted name: tRNA pseudouridine32 synthase
Reaction: tRNA uridine32 = tRNA pseudouridine32
Other name(s): RluA (ambiguous); pseudouridine synthase RluA (ambiguous); Pus9p; Rib2/Pus8p
Systematic name: tRNA-uridine32 uracil mutase
Comments: The dual-specificity enzyme from Escherichia coli also catalyses the formation of pseudouridine746 in 23S rRNA [5]. cf. EC (23S rRNA pseudouridine746 synthase).
