Researchers have made a significant advance toward the goal of using bacteria—rather than fossil fuels—to produce ethylene, a key chemical in the production of many plastics. Subscribe to our ...

While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...

Gene editing is one of the latest breakthroughs in biology. The widely known CRISPR-Cas gene editing system provided prokaryotes (organisms that lack cell nuclei) an immunity against foreign DNA.

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up biochemical reactions (catalysis) in cells—have adapted to the habitats of ...

Malathy Palayam, Aleczander Young, Lior Tal, and Nitzan Shabek at the UC Davis Department of Plant Biology are exploring the mechanism by which the plant hormone strigoractone regulates a massive ...

Cutinases are fungal enzymes that naturally degrade plant cuticles and show promise for recycling plastics. However, they ...

Scientists used x-rays to decipher the three-dimensional structure of the main protease of the virus that causes COVID-19 at different temperatures. The background image shows the full structure at ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...
