Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up ...

Enzyme activation typically happens when small molecules bind outside the active site, to increase the enzyme’s activity. What’s special about the enzyme you investigated, 8-oxoguanine DNA ...

Enzymes lower the activation energy necessary to transform a reactant into a product. On the left is a reaction that is not catalyzed by an enzyme (red), and on the right is one that is (green).

Enzymes originally evolved in high-temperature environments and later adapted to lower temperatures as Earth cooled. Scientists discovered that a key shift in enzyme function occurred over ...

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 ...
