Bacterial chemotaxis is a sophisticated behavioural process that enables microorganisms to navigate toward favourable environments by detecting subtle differences in chemical gradients. At the heart ...

Two-component signal transduction systems (TCS) are fundamental to the ability of bacteria and certain lower eukaryotes to sense and respond to environmental changes. Typically composed of a sensor ...

This paper describes the isolation, cloning, and molecular characterization of a receptor molecule for calcium ions located on the outer surface of certain types of cells. The reason it has received ...
