34551042-0	2021	Biliverdin chiral derivatives as chiroptical switches for pH and metal cation sensing.	Biliverdine	0-10	phenylalanine hydroxylase	Homo sapiens	58-60	
34551042-7	2021	We envision the use of current chiroptical spectroscopies in connection with chiral biliverdin derivatives as natural sensors or probes of the micro-environmental conditions, such as pH or the presence of metal ions.	Biliverdine	84-94	phenylalanine hydroxylase	Homo sapiens	183-185
