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 ...

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

When nucleic acids like DNA or RNA build up in a cell's cytoplasm, it sets off an alarm call for the immune system. Enzymes usually clear these nucleic acids before they cause an issue, but when these ...

Scientists discovered hundreds of energy-making enzymes secretly working on human DNA—revealing a hidden “mini-metabolism” ...

While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...

Specific glycans attached to the GnT-IVa and GnT-IVb can bind to the enzyme’s ligand-binding site, interfering with recognition and binding to the glycosylation proteins’ normal glycoprotein ...

Scientists have prototyped a new method for 'rationally engineering' enzymes to deliver improved performance. They have devised an algorithm, which takes into account an enzyme's evolutionary history, ...

Nitrilases are a unique class of enzymes that catalyse the hydrolysis of nitrile compounds to yield the corresponding carboxylic acids or amides. Their application in biotransformation processes has ...

Researchers have captured real-time "molecular movies" showing how an enzyme changes shape during catalysis. The study was published in Nature Communications. Subscribe to our newsletter for the ...

The snapshots reveal key reactions steps. At 0 ms, water molecules occupy the substrate-binding site. At 50 ms, a substrate-cofactor intermediate forms. At 100 ms, the product is released, and the ...
