Reaction: alanine + tRNA(Ala) + ATP => Ala-tRNA(Ala) + AMP + pyrophosphate
- in pathway: Mitochondrial tRNA aminoacylation
AARS2 (mitochondrial alanyl tRNA synthetase) catalyzes the reaction of alanine, mitochondrial tRNA(Ala), and ATP to form Ala-tRNA(Ala), AMP, and pyrophosphate. The AARS2 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).
