Enzymes are proteins – large molecules that do the behind-the-scenes work that keep all living things alive. These proteins are made up of amino acids, a set of building blocks that can be stitched ...

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 ...

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.

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 ...

The way that plants process nutrients has a rich back story—they rely on enzymes that have been evolving for billions of years. However, these enzymes are often loosely understood, leaving ...

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 ...
