ATP Binding to Amyloid Fibrils Reduces Cellular Toxicity by Altering Protein Structure

Researchers identified a mechanism in a 2026 study published in *Cell Death Discovery* where adenosine triphosphate (ATP) binds to amyloid fibrils and alters their structural composition, resulting in a decrease in cellular toxicity. The study examined how ATP interacts with fibrils formed by lysozyme and superfolder green fluorescent protein (sfGFP) to modify their physical state.

The investigation demonstrates that ATP acts as a biological agent capable of remodeling these protein aggregates. By binding to the amyloid fibrils, ATP changes their structural configuration, which subsequently mitigates the harmful effects typically associated with these protein structures in biological systems. These findings provide new data regarding the functional roles of ATP beyond its traditional use as an energy source, specifically highlighting its influence on protein aggregation and cellular health.
