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, ...

Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up biochemical reactions (catalysis) in cells—have adapted to the habitats of ...

Macrolides are an important class of antibiotics that includes drugs such as azithromycin and erythromycin, which are widely ...

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 ...

Scientists have discovered a new function in a plant enzyme that could inspire the design of new chemical catalysts. The enzyme catalyzes, or initiates, one of the cornerstone chemical reactions ...

A new artificial intelligence tool can predict the functions of enzymes based on their amino acid sequences, even when the enzymes are unstudied or poorly understood. The researchers said the AI tool, ...
