Chemical Conformation of the Essential Glutamate Site of the c-Ring within Thermophilic Bacillus FoF1-ATP Synthase Determined by Solid-State NMR Based on its Isolated c-Ring Structure
Chemical Conformation of the Essential Glutamate Site of the c-Ring within Thermophilic Bacillus FoF1-ATP Synthase Determined by Solid-State NMR Based on its Isolated c-Ring Structure
Proton translocation through the membrane-embedded F(o) component of F-type ATP synthase (F(o)F(1)) is facilitated by the rotation of the F(o) c-subunit ring (c-ring), carrying protons at essential acidic amino acid residues. Cryo-electron microscopy (Cryo-EM) structures of F(o)F(1) suggest a unique proton translocation mechanism. To elucidate it based on the chemical conformation of the essential acidic residues of the c-ring in F(o)F(1), we determined the structure of the isolated thermophilic...
