Term Name:	3,4-didehydroretinal binding
Synonyms:	blue-sensitive opsin, green-sensitive opsin, long-wave-sensitive opsin, opsin, red-sensitive opsin, short-wave-sensitive opsin, UV-sensitive opsin, violet-sensitive opsin
Definition:	Binding to 3,4-didehydroretinal, a form of retinal that plays a role in the visual process in freshwater fish and some amphibians analogous to that of all-trans retinal in other vertebrates. 3,4-didehydro-11-cis-retinal combines with an opsin to form cyanopsin (cone) or porphyropsin (rod).
