Enables pseudouridine synthase activity. Involved in tRNA pseudouridine synthesis. Located in mitochondrion. Orthologous to human RPUSD2 (RNA pseudouridine synthase domain containing 2).
SGD Description
Mitochondrial tRNA:pseudouridine synthase; catalyzes the formation of pseudouridine at position 32 in mitochondrial tRNAs; contains an N-terminal mitochondrial targeting sequence; PUS9 has a paralog, RIB2, that arose from the whole genome duplication
