Bacteriophytochrome

UniProtKB accession:  Q9RZA4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Photoreceptor which exists in two forms that are reversibly interconvertible by light: the R form that absorbs maximally in the red region of the spectrum and the FR form that absorbs maximally in the far-red region. Has also a slight blue shift for the far-red maximum. Could also absorb green light. May participate in regulating pigment synthesis like the carotenoid deinoxanthin which could protect the bacterium from intense visible light.
