Sulfur-reducing bacteria of the phylum Desulfobacterota play a crucial role in the global biogeochemical sulfur cycle. Species such as Geobacter sulfurreducens use elemental sulfur as a terminal ...
In high school biology, enzymes are introduced as "biological catalysts that accelerate chemical reactions."However, enzyme research at the university level goes far beyond that.Observing the ...
A deep-sea microbe uses an exceptionally heat-resistant enzyme to turn atmospheric nitrogen into ammonia at temperatures that would destroy most proteins. Its unusual structure and a newly observed ...
Sir2, an enzyme belonging to sirtuins, has been shown to be involved in the deacetylation of proteins. Researchers from the Institute of Science Tokyo reveal that a tandem allosteric effect of ...
Enzymes are often described as molecular machines that recognize and process specific molecules. However, they are not rigid structures. Their shapes can change, affecting how molecules enter, ...
Reactions that can combine more than two molecular pieces in one go are a powerful way to build complexity quickly and save on costly isolation and purification. But the choreography for such a ...
Here the authors characterise two botulinum-like toxins, PG1 and PG2. Their light chains cut a key protein in fruit flies; PG1 is toxic even without its heavy chain. PG1 has a distinct compact ...
One of the major challenges in treating the most common subtype of breast cancer (hormone receptor positive, HR+) is the ...
Sir2, an enzyme belonging to sirtuins, has been effectively involved in the deacetylation of proteins. A tandem allosteric effect of reactant and product is responsible for the efficient deacetylation ...
On September 23, 2026, Anthropic announced that "Claude discovered a previously unknown enzyme mechanism within viral DNA" ...
The very cells that created us may have a role in saving our lives. Scientists have always been amazed by the energy production system in a sperm’s tail. The system drives flagellar movement and is ...
