Accepted name: 23S rRNA pseudouridine1911/1915/1917 synthase
Reaction: 23S rRNA uridine1911/uridine1915/uridine1917 = 23S rRNA pseudouridine1911/pseudouridine1915/pseudouridine1917
Other name(s): RluD; pseudouridine synthase RluD
Systematic name: 23S rRNA-uridine1911/1915/1917 uracil mutase
Comments: Pseudouridine synthase RluD converts uridines at positions 1911, 1915, and 1917 of 23S rRNA to pseudouridines. These nucleotides are located in the functionally important helix-loop 69 of 23S rRNA [1].
