TL;DR: It is shown that the single 8U→C mutation leads to a failure of the tRNA to respond conformationally to Mg2+. (via Semantic Scholar)

TL;DR: Investigation of functional folding interactions of chemically synthesized and site-specifically modified mitochondrial and cytoplasmic tRNAs finds that Mg2+ is critical for folding of the truncated D-domain of bovine mtRNAMet with the tRNA's T-domain and indicates that conserved modifications assist and stabilize the formation of the functional mtRNA tertiary structure.
