A resurrected ancient enzyme is helping scientists test how reliably Earth’s oldest rocks record signs of life.

Enzymes catalyze chemical reactions to create products from substrates, binding them through a lock-and-key mechanism where substrates bind to specific active sites. Through this video, learn more ...

Frances Arnold's game-changing technique of "directed evolution" creates enzymes with unusual capabilities. Her own evolution made it possible.

Imagine trying to bake a cake without heat. You’ve got all the ingredients like flour, eggs and sugar, but nothing is happening. That’s what your body would be like without enzymes: potential but no ...

Scientists discovered hundreds of energy-making enzymes secretly working on human DNA—revealing a hidden “mini-metabolism” ...

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 ...
