== Function ==
[https://www.uniprot.org/uniprot/BACR1_HALWD BACR1_HALWD] Light-driven proton pump. The chromophore contains 78% all-trans- and 22% 13-cis-retinal in the dark and 90% all-trans- and 10% 13-cis-retinal upon illumination with >500 nm light.<ref>PMID:21135094</ref> <ref>PMID:22248212</ref> <ref>PMID:23720753</ref>
