3.E.1.1.3
"Middle" rhodopsin or bacteriorhodopsin 1 (Brhol); it has 11-cis-retinal and shows intermediate properties between Brho and sensory rhodopsin II (Sudo et al., 2011). Its structure is known to 2.0 Å resolution following crystalization using polymer-bounded lipid nanodiscs (Broecker et al. 2017). It may pump Cl- and Br- into the cell (Kikukawa 2021). See also Ko et al. 2022.
