BlsA Is a Low to Moderate Temperature Blue Light Photoreceptor in the Human Pathogen .

Light is an environmental signal that produces extensive effects on the physiology of the human pathogen . Many of the bacterial responses to light depend on BlsA, a bluelight using FAD (BLUF)-type photoreceptor, which also integrates temperature signals. In this work, we disclose novel mechanistic aspects of the function of BlsA.
