病気の変異を持ったままでも光明が見えてきた —— tRNA 修飾酵素でミトコンドリア病の治療を目指す —— [発表のポイント] 細胞中のごく微量なミトコンドリア tRNA中の化学修飾塩基を高感度に検出・定量する方法を開発しまた。 ミトコンドリア ...

理化学研究所（理研）脳神経科学研究センタータンパク質構造疾患研究チームのチェンウェン・チェン研究員と田中元雅チームリーダーの研究チームは、タンパク質合成中の転移RNA（tRNA）[1] の種類や量を詳しく解析する「tRNAリボソームプロファイリング法 ...

New results from ultrafast spectroscopy and in-depth theoretical calculations demonstrate that the complex folded structure of tRNA is stabilized by magnesium ions in direct contact with phosphate ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...

Archaeosine is synthesized via three steps in tRNA. ArcS, the second-step enzyme, transfers a lysine to preQ 0, which is introduced into tRNA by ArcTGT, the first-step enzyme. The resultant preQ 0-Lys ...

Imagine your body as a highly organised factory where workers tirelessly assemble proteins around the clock. These proteins are the machines and scaffolds that make up your body and are essential for ...

A groundbreaking study has shed light on the critical role of a tRNA methylation enzyme, TRMT10A, in supporting brain function. The findings reveal how the absence of TRMT10A leads to a reduction in ...

Prostate cancer is the second-most common cancer in men. A new study from Thomas Jefferson University uncovered a new potential therapeutic target in tiny molecules called tRNA halves. "Because tRNA ...
