Mitochondrial tRNA pseudouridine27/28 synthase

Mitochondrial tRNA pseudouridine27/28 synthase (, Pus2, Pus2p, RNA:pseudouridine synthases 2) is an enzyme with systematic name mitochondrial tRNA-uridine27/28 uracil mutase. This enzyme catalyses the following chemical reaction


 * mitochondrial tRNA uridine27/28 $$\rightleftharpoons$$ mitochondrial tRNA pseudouridine27/28

The mitochondrial enzyme Pus2p is specific for position 27 or 28 in mitochondrial tRNA.
