WebMar 23, 2024 · First, aaRSs evolving to charge new tRNA substrates may require changes to key regions involved in recognition of tRNA “identity elements” (Giegé et al. 1998; Igloi 2024, 2024). Second, mitochondria differ from the cytosol in numerous respects (e.g., osmotic conditions) that could potentially affect protein folding and tRNA interactions ... WebThe gene for valyl-tRNA synthetase (ValRS) (valS) from Escherichia coli was first cloned in 1984. 1 In 1987, the yeast ValRS gene (VAS1) was sequenced, and it was reported that the encoded polypeptide shows high homology …
WebAminoacyl-tRNA synthetases (aaRSs) are essential components for mRNA translation. Two sets of aaRSs are required for cytoplasmic and mitochondrial translation in vertebrates. Interestingly, TARSL2 is a recently evolved duplicated gene of TARS1 (encoding cytoplasmic threonyl-tRNA synthetase) and repr … WebReplication of human immunodeficiency virus type 1 (HIV-1) requires the packaging of tRNALys,3 from the host cell into the new viral particles. The GagPol viral polyprotein precursor associates with mitochondrial lysyl-tRNA synthetase (mLysRS) in a complex with tRNALys, an essential step to initiate reverse transcription in the virions.
