In all living organisms, the biomolecule transfer RNA (tRNA) plays a fundamental role in protein production. tRNAs are generated from precursor molecules in several steps. The enzyme tRNA splicing ...
The structure of a key enzyme involved in protein production is revealed by cryo-electron microscopy (cryo-EM). Using cryo-EM, researchers at Goethe University (Frankfurt, Germany) shed light on ...
Among the tRNA population of the archaeal parasite Nanoarchaeum equitans are five species assembled from separate 5' and 3' tRNA halves and four species derived from tRNA precursors containing introns ...

tRNA ligase glues tRNA halves together. This image relates to an article that appeared in the Feb. 11, 2011, issue of Science, published by AAAS. The study, by Dr. Johannes Popow at Molecular ...
Overview of RNA repair – There is an emerging appreciation of the existence of “RNA repair” pathways that rely on RNA ligases to maintain or manipulate RNA structure in response to purposeful RNA ...
Before RNA and after : geophysical and geochemical constraints on molecular evolution / Stephen J. Mojzsis, Ramanarayanan Krishnamurthy, and Gustaf Arrhenius -- Prospects for understanding the origin ...
