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

Uteroplacental insufficiency and subsequent intrauterine growth retardation (IUGR) affects postnatal metabolism. In juvenile rats, IUGR alters skeletal muscle mitochondrial gene expression and reduces ...

One of these enzymes from white blood cells, known as MMP12, does not remain outside of cells while it fights infections, but rather it can travel all the way to the center of cells. Understanding how ...

Here we describe a high-throughput, quantitative method for the isolation of enzymes with novel substrate specificities from large libraries of protein variants. Protein variants are displayed on the ...

Doctors have long treated heart attacks, improved asthma symptoms and cured impotence by increasing levels of a single molecule in the body: nitric oxide. The tiny molecule can change how proteins ...

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 ...

Synthetic biology is a growing field of research that is aiming to create a new kind of organism. Engineering synthetic proteins that can perform simple cellular functions as they would in real life ...
