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, ...

A research team from The Hong Kong University of Science and Technology (HKUST) has made an advance in understanding the molecular machinery of RNA silencing. The team uncovered how the human enzyme ...

A metabolic enzyme studied for over seven decades has a hidden second function—it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, ...

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 ...

A multi-enzyme platform is developed for sequence-unconstrained traceless protein synthesis and modification with either synthetic peptides or recombinant proteins, according to a new study out of ...

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. Researchers said the AI tool, ...
