WebTransfer RNA (tRNA) molecules are sumptuously decorated with evolutionary conserved post-transcriptional nucleoside modifications that are essential for structural stability and ensure efficient protein translation. WebOur results suggest that loss of 2-thiolation follows accumulation of newly synthesized tRNA that lack s (2)U34 modification due to temperature sensitivity of the URM1 pathway in S. cerevisiae and S. bayanus. Furthermore, our analysis of the tRNA modification pattern in selected yeast species revealed two alternative phenotypes. glenayr road toronto
