Similarity of a chromatic adaptation sensor to phytochrome and ethylene receptors.
Complementary chromatic adaptation in cyanobacteria acts through photoreceptors to control the biosynthesis of light-harvesting complexes. The mutant FdBk, which appears black, cannot chromatically adapt and may contain a lesion in the apparatus that senses light quality. The complementing gene identified here, rcaE, encodes a deduced protein in which the amino-terminal region resembles the chromophore attachment domain of phytochrome photoreceptors and regions of plant ethylene receptors; the carboxyl- terminal half is similar to the histidine kinase domain of two-component sensor kinases.
