The Mechanism of ATP Synthesis

©1999 Timothy Paustian, University of Wisconsin-Madison

ATP synthase is driven by proton exchanges on subunit c. It is thought that when subunit c moves near subunit a, it interacts with it, losing a proton off an acidic amino acid. The released proton moves into the cytoplasm. A new proton from the periplasm enters through a channel in subunit a and interupts this interaction, causing subunit c to move away from subunit a and turning F1 relative to F0.
