Description

AI-generatedUnreviewed
This family of proteins includes photoreceptors known as bacteriophytochromes and components of two-component regulatory systems. Bacteriophytochromes are light-sensitive and exist in two forms that are interconvertible by light, with absorption maxima in the red and far-red regions of the spectrum. They may also absorb green light and are implicated in regulating pigment synthesis for protection against intense light. The two-component system proteins function as final receptors in regulatory pathways responding to environmental stimuli, such as osmolarity changes or oxidative stress. They control downstream signaling cascades, which can lead to various cellular responses including adaptation to osmotic stress, cell wall biosynthesis, and virulence in pathogenic species. These proteins can be phosphorylated or unphosphorylated, with their activity and stability regulated accordingly to modulate the signaling pathways.
