Biliverdin binds covalently to agrobacterium phytochrome Agp1 via its ring A vinyl side chain.

The Journal of biological chemistry - 5 Sept 2003

Abstract excerpt

The widely distributed phytochrome photoreceptors carry a bilin chromophore, which is covalently attached to the protein during a lyase reaction. In plant phytochromes, the natural chromophore is coupled by a thioether bond between its ring A ethylidene side chain and a conserved cysteine residue within the so-called GAF domain of the protein. Many bacterial phytochromes carry biliverdin as natural chromophore,...
