30755663-1	2019	Phytochromes are red/far-red light sensing photoreceptors employing linear tetrapyrroles as chromophores, which are covalently bound to a cysteine (Cys) residue in the chromophore-binding domain (CBD, composed of a PAS and a GAF domain).	Tetrapyrroles	75-88	fibroblast growth factor 9	Homo sapiens	225-228	
18846279-4	2008	They are characterized by the presence of a chromophore-binding GAF domain that is homologous to the tetrapyrrole-binding GAF domain of the phytochrome.	Tetrapyrroles	101-113	fibroblast growth factor 9	Homo sapiens	64-67
