25 June 2024 In the front, a 3D model of three molecules bound together: METTL6 in (orange), serine tRNA synthetase in (shades of lilac) and serine tRNA (black). In the background an illustration of a construction site. Two trucks with ‘UGA’ and ‘AGA’ written on them are visible at the bottom.

An enzyme with a smart friend

EMBL Grenoble’s Kowalinski Group analysed the structure of an enzyme responsible for modifying tRNA molecules to fine-tune protein production. They discovered that to distinguish almost identical, yet different, tRNA molecules, the enzyme uses help from another enzyme – a type of cooperation…

Above it is a drawing of nucleic acid with arrows connecting nitrogenous bases to different points in the protein complex. On the right: a line with peaks indicating the peaks recorded in mass spectrometry. Above two peaks, there are smaller depictions of the doughnut-shaped complex, one with a blue element and one without.

RNA to rule them all

The Kosinski Group at EMBL Hamburg collaborated with other groups in Hamburg to reveal critical steps in Lassa virus ribonucleoparticle assembly and recruitment, and the crucial role played by RNA in in the Lassa virus life cycle.

19 December 2023 Cartoon showing nanoparticles on a conveyer belt passing through a machine. They are ordered by size and the smallest one pass through the machine before the bigger ones. A ray of light enters the machine, where a nanoparticle is being scanned, and leaves it on the other side. A monitor on top of the scanning machine shows an X-ray of a nanoparticle.

‘X-ray vision’ for investigation of mRNA nanomedicines

EMBL Hamburg, Johannes Gutenberg University Mainz, Postnova Analytics GmbH, and BioNTech SE have developed a new method to quantitatively investigate sizes of nanoparticles containing mRNA. It may become an important part of regular characterisation of mRNA nanomedicines in the future.
