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 ...

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 ...

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

If enzymes are heated too much or put into a higher or lower pH, their shape can change. The enzyme undertakes a process of denaturation, meaning it will not fit its substrate or substrates.

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 ...

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 ...

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 ...
