Reaction: valine + tRNA(Val) + ATP => Val-tRNA(Val) + AMP + pyrophosphate
- in pathway: Mitochondrial tRNA aminoacylation
VARS2 (mitochondrial valyl tRNA synthetase) catalyzes the reaction of valine, mitochondrial tRNA(val), and ATP to form Val-tRNA(Val), AMP, and pyrophosphate. The VARS2 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).
