Mutation Study of Heliorhodopsin 48C12.

Abstract excerpt

Rhodopsins are heptahelical transmembrane photoactive protein families: type 1 (microbial rhodopsins) and type 2 (animal rhodopsins). Both families share similar topologies and chromophore retinal, which is linked covalently as a protonated Schiff base to a Lys at the transmembrane 7 helix. Recently, through functional metagenomics analysis, we reported an unnoticed diverse family, heliorhodopsins (HeRs), which...
