mitochondrial tryptophanyl-tRNA aminoacylation
mitochondrial tryptophanyl-trna aminoacylation
The process of coupling tryptophan to tryptophanyl-tRNA in a mitochondrion, catalyzed by tryptophanyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA.
