aspartate + tRNA(Asp) + ATP => Asp-tRNA(Asp) + AMP + pyrophosphate (R-HSA-380229) [Homo sapiens]

Reaction
Summation

DARS2 (mitochondrial aspartyl tRNA synthetase) catalyzes the reaction of aspartate, mitochondrial tRNA(Asp), and ATP to form Asp tRNA(Asp), AMP, and pyrophosphate. The enzyme, a class II tRNA synthetase, is a homodimer (Bonnefond et al. 2005). Homozygosity for DARS2 mutations is associated with leukoencephalopathy with brainstem and spinal cord involvement plus lactate elevation (Scheper et al 2007).
