Reaction: threonine + tRNA(Thr) + ATP => Thr-tRNA(Thr) + AMP + pyrophosphate
- in pathway: Mitochondrial tRNA aminoacylation
TARS2 (mitochondrial threonyl tRNA synthetase) catalyzes the reaction of threonine, mitochondrial tRNA(Thr), and ATP to form Thr-tRNA(Thr), AMP, and pyrophosphate. The TARS2 gene has been identified by computational analysis of the human genome sequence; its function has been inferred from those of the biochemically characterized mitochondrial aspartyl and tyrosyl tRNA synthetases (Bonnefond et al. 2005).
