CC   -!- FUNCTION: This photoactive protein is a photoreceptor with kinetics
CC       similar to that of rhodopsin. {ECO:0000250}.
CC   -!- PTM: The 4-hydroxycinnamic acid (p-coumaric acid) chromophore is
CC       covalently bound via a thioester linkage. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the photoactive yellow protein family.
CC       {ECO:0000305}.
