Scientists get detailed glimpse of chemoreceptor architecture in bacterial cells

Using state-of-the-art electron microscopy techniques, a team led by researchers from Caltech has for the first time visualized and described the precise arrangement of chemoreceptors -the receptors that sense and respond to chemical stimuli -in bacteria. In addition, they have found that this specific architecture is the same throughout a wide variety of bacterial species, which means that this is a stable, universal structure that has been conserved over evolutionary time.
