This article needs attention from an expert in archaea. The specific problem is: historical bacteria->archaea classification change.
Bacterial rhodopsins are a family of bacterial opsins. They are retinal-binding proteins that provide light-dependent ion transport and sensory functions to a family of halophilic [1 ] and other bacteria. They are integral membrane proteins with seven transmembrane helices, the last of which contains the attachment point for [2 ] retinal (a conserved lysine).
The proteins from
halobacteria include bacteriorhodopsin and archaerhodopsin, which are light-driven proton pumps; halorhodopsin, a light-driven chloride pump; and sensory rhodopsin, which mediates both photoattractant (in the red) and photophobic (in the ultra-violet) responses. Proteins from other bacteria include proteorhodopsin.
