Abstract excerpt
In this report, we investigated the pathophysiology of a novel hypertension-associated mitochondrial tRNA(Ala) 5655A → G (m.5655A → G) mutation. The destabilization of a highly conserved base pairing (A1-U72) at the aminoacyl acceptor stem by an m.5655A → G mutation altered the tRNA(Ala) function. An in vitro processing analysis showed that the m.5655A → G mutation reduced the efficiency of tRNA(Ala) precursor 5'...
