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

Science & Technology 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…

Understanding the mechanisms of enzyme catalysis

Science & Technology Enzymes constitute a large fraction of genomes – 20% in humans – which makes them a very important part of life. Despite decades of studies and a rich literature dedicated to understanding the reaction mechanisms of enzymes, the rules of enzyme catalysis are still not fully clear. A new…

Two in one

In a paper published online today in PNAS, scientists from the European Molecular Biology Laboratory (EMBL) in Hamburg, Germany, reveal new insights into the workings of enzymes from a group of bacteria including Mycobacterium tuberculosis, the bacterium that causes tuberculosis. The new findings…

Raising the alarm when DNA goes bad

Our genome is constantly under attack from things like UV light and toxins, which can damage or even break DNA strands and ultimately lead to cancer and other diseases. Scientists have known for a long time that when DNA is damaged, a key enzyme sets off a cellular ‘alarm bell’ to alert the…

Sugarcoating fruit fly development

Proteins are the executive agents that carry out all processes in a cell. Their activity is controlled and modified with the help of small chemical tags that can be dynamically added to and removed from the protein. 25 years after its first discovery, researchers at the European Molecular Biology…

New findings reveal how influenza virus hijacks human cells

Influenza is and remains a disease to reckon with. Seasonal epidemics around the world kill several hundred thousand people every year. In the light of looming pandemics if bird flu strains develop the ability to infect humans easily, new drugs and vaccines are desperately sought. Researchers at…

Researchers shed light on shrinking of chromosomes

A human cell contains an enormous 1.8 metres of DNA partitioned into 46 chromosomes. These have to be copied and distributed equally into two daughter cells at every division. Condensation, the shortening of chromosomes, allows the cell to handle such huge amounts of genetic material during cell…

A link between our body’s energy levels and a protein that wraps our DNA?

Living organisms need to sense the amount of energy that is available to them and regulate the activity of their genes accordingly. Scientists have made the unexpected finding that a histone protein, which wraps DNA into tight bundles and regulates gene activity, can bind a small molecule produced…
