TRNA pseudouridine38/39 synthase

tRNA pseudouridine38/39 synthase (, Deg1, Pus3p, pseudouridine synthase 3) is an enzyme with systematic name tRNA-uridine38/39 uracil mutase. This enzyme catalyses the following chemical reaction


 * tRNA uridine38/39 $$\rightleftharpoons$$ tRNA pseudouridine38/39

The enzyme from Saccharomyces cerevisiae is active only towards uridine38 and uridine39.
