Aqueous Access Pathways in ATP Synthase Subunit a: REACTIVITY OF CYSTEINE SUBSTITUTED INTO TRANSMEMBRANE HELICES 1, 3, AND 5

Subunit a is thought to play a key role in H⁺ transport-driven rotation of the subunit c ring in Escherichia coli F₁F₀ ATP synthase. In the membrane-traversing F₀ sector of the enzyme, H⁺ binding and release occurs at Asp-61 in the middle of the second transmembrane helix (TMH) of subunit c. Protons...
