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

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

Annotations of enzyme function provide critical starting points for generating and testing biological hypotheses, but the quality of functional annotations is hindered by uncertain assignments for ...

Enzymes help with specific functions that are vital to the operation and overall health of the human body. They help speed up chemical reactions and are essential for respiration, digestion, muscle ...

Scientists first observed the biological phenomenon of restriction and modification in the 1950s, but they did not identify and isolate restriction enzymes until the late 1960s. 3 In 1970, Hamilton ...

Usually enzyme complexes make multistep processes easier by catalyzing sequential reactions in which the product of one enzyme becomes the substrate for the next. In a new finding, researchers report ...

Successful cancer surgery depends on a surgeon’s ability to remove tumors, while minimizing harm to healthy tissues. Surgeons currently use glowing dyes which mark cancer cells to help differentiate ...

Here's what enzymes are, what they do and how you'll know if you are ever low on them.
