Is responsible for the charging of tRNA(Phe) with phenylalanine in mitochondrial translation. To a lesser extent, also catalyzes direct attachment of m-Tyr (an oxidized version of Phe) to tRNA(Phe), thereby opening the way for delivery of the misacylated tRNA to the ribosome and incorporation of ROS-damaged amino acid into proteins. . This is the function of Ensembl gene identifier ENSG00000145982 (FARS2, phenylalanyl-tRNA synthetase 2, mitochondrial).
