Engineered starfish oocytes shape-shift in response to light, may enable the design of synthetic, light-activated cells for ...

Cells constantly shift and transform, triggering the complex choreography that shapes living organisms. Whether dividing into ...

Life takes shape with the motion of a single cell. In response to signals from certain proteins and enzymes, a cell can start to move and shake, leading to contractions that cause it to squeeze, pinch ...

The researchers observed that light activated the enzyme, causing predictable cell movements. For example, specific light ...

This monomer inhibits the enzyme with high affinity (K i = 40 μM) holding it in place near the growing particle and hence allowing the polymer chains to adapt to the shape of the protein surface ...

Using computational tools and virtual screening, researchers at the Center for Redox Processes in Biomedicine (Redoxoma) have identified new inhibitors of the enzyme human 15-lipoxygenase-2 (h15-LOX-2 ...

MIT scientists have discovered a way to control the movements of starfish cells using light, which could have biomedical applications.

Researchers use light stimuli to shape cells and develop a model that explains the mechanisms – with implications for synthetic biology.

Different enzymes contain up to 20 different amino acids linked together to form a chain which then folds into the globular enzyme shape. Enzymes have active sites which only match specific ...

Enzymes are proteins that can change shape and therefore become active or inactive. An activator molecule (green pentagon) can bind to an enzyme (light green puzzle shape) and change its overall ...

In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of the substrate molecule, or molecules. This is essential to the enzyme being able to work.

How does your body speed up these important reactions? The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a ...
