Replaceability of Schiff base proton donors in light-driven proton pump rhodopsins
Many H(+)-pump rhodopsins conserve “H(+) donor” residues in cytoplasmic (CP) half channels to quickly transport H(+) from the CP medium to Schiff bases at the center of these proteins. For conventional H(+) pumps, the donors are conserved as Asp or Glu but are replaced by Lys in the minority, such a...
