D001436	Bacteriorhodopsins	Rhodopsins found in the PURPLE MEMBRANE of halophilic archaea such as HALOBACTERIUM HALOBIUM. Bacteriorhodopsins function as an energy transducers, converting light energy into electrochemical energy via PROTON PUMPS.	Bacteriorhodopsin
D012172	Retinaldehyde	A diterpene derived from the carotenoid VITAMIN A which functions as the active component of the visual cycle. It is the prosthetic group of RHODOPSIN (i.e., covalently bonded to ROD OPSIN as 11-cis-retinal). When stimulated by visible light, rhodopsin transforms this cis-isomer of retinal to the trans-isomer (11-trans-retinal). This transformation straightens-out the bend of the retinal molecule and causes a change in the shape of rhodopsin triggering the visual process. A series of energy-requiring enzyme-catalyzed reactions convert the 11-trans-retinal back to the cis-isomer.	11-trans-Retinal,3,7-dimethyl-9-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4,6,8-Nonatetraenal,Axerophthal,Retinal,Retinene,Retinyl Aldehydde,Vitamin A Aldehyde,all-trans-Retinal,11-cis-Retinal,11 cis Retinal,11 trans Retinal,Aldehydde, Retinyl,Aldehyde, Vitamin A,all trans Retinal
