Mitochondrial tRNA pseudouridine^27/28 synthase (EC 5.4.99.44, Pus2, Pus2p, RNA:pseudouridine synthases 2) is an enzyme with systematic name mitochondrial tRNA-uridine^27/28 uracil mutase.^[1] This enzyme catalyses the following chemical reaction

mitochondrial tRNA uridine^27/28

\rightleftharpoons

mitochondrial tRNA pseudouridine^27/28

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