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 ...

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 ...

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).

An optogenetic method for controlling the movement of starfish oocytes has been developed, which could have applications for ...

You may have heard of the fantastic-sounding "dark side of the genome." This poorly studied fraction of DNA, known as ...

Enzymes initially developed in high-temperature environments and subsequently adapted to cooler conditions as the Earth underwent a cooling phase.

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

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 ...

Enzymes are biological catalysts that lower the activation energy of chemical reactions, allowing them to proceed at a faster rate. This illustration depicts the process of enzyme catalysis. The ...

That’s why she and her group teamed up with machine-learning-for-chemistry expert Gabe Gomes and his group at Carnegie Mellon ...

This is done through a multi-step process where the enzymes activate amino acid building blocks and convert them into elongated peptides. Because of their large size, complex design and changing ...

cGAMP functioned as an endogenous second messenger to activate downstream signaling events that trigger antiviral immunity. However, Chen wanted to figure out the enzyme that made cGAMP. Through ...
