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, ...

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 ...

The protein community is awash in data. As of October, the UniProt database of protein sequences had more than 44 million entries. UniProt serves as a clearinghouse for sequences. Researchers who ...

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 ...

Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and ...

Protein motions and structural dynamics play an important role in the evolution of new enzyme functions, an international team reports. Undertaking the process in both directions helps elucidate the ...

Chemists at Umeå University have succeeded in mapping structures and functions of a transient enzyme state. By modifying the enzyme adenylate kinase, researchers were able to isolate the molecule and ...
