23S rRNA pseudouridine2457 synthase

23S rRNA pseudouridine2457 synthase (, RluE, YmfC) is an enzyme with systematic name 23S rRNA-uridine2457 uracil mutase. This enzyme catalyses the following chemical reaction


 * 23S rRNA uridine2457 $$\rightleftharpoons$$ 23S rRNA pseudouridine2457

The enzyme modifies uridine2457 in a stem of 23S RNA in Escherichia coli.
