NUS-led research team discovers how bacteria sense salt stress
Date:7/9/2012

e less spring-like the protein, the higher is its activity. This protein movement may provide a unified model of how bacteria sense their environment.

Application of the phenomenon

This study is an example of basic science with immediate applications. Recognising that diverse proteins operate as molecular springs whose spring-like movement can be dampened is fundamental to understanding how these proteins work. This study also underscores the role of water in biology. It demonstrates how salts and sugars can alter biological properties of proteins through the effects on water and is relevant for understanding life processes across species from bacteria to humans.

Further research

The NUS research team is now working on studying the protein in its native membrane by embedding the bacterial sensor protein in an artificial membrane. They hope to understand how the membrane contributes to overall protein activity, structure, stability and responses to salts.
