Citation | Journal: Nat Commun / Year: 2025Title: Engineering of ATP synthase for enhancement of proton-to-ATP ratio. Authors: Hiroshi Ueno / Kiyoto Yasuda / Norie Hamaguchi-Suzuki / Riku Marui / Naruhiko Adachi / Toshiya Senda / Takeshi Murata / Hiroyuki Noji / ![]() Abstract: FF-ATP synthase (FF) interconverts the energy of the proton motive force (pmf) and that of ATP through the mechanical rotation. The H/ATP ratio, one of the most crucial parameters in bioenergetics, ...FF-ATP synthase (FF) interconverts the energy of the proton motive force (pmf) and that of ATP through the mechanical rotation. The H/ATP ratio, one of the most crucial parameters in bioenergetics, varies among species due to differences in the number of H-binding c-subunits, resulting in H/ATP ratios ranging from 2.7 to 5. In this study, we seek to significantly enhance the H/ATP ratio by employing an alternative approach that differs from that of nature. We engineer FF to form multiple peripheral stalks, each bound to a proton-conducting a-subunit. The engineered FF exhibits an H/ATP ratio of 5.8, surpassing the highest ratios found in naturally occurring FFs, enabling ATP synthesis under low pmf conditions where wild-type enzymes cannot synthesize ATP. Structural analysis reveals that the engineered FF forms up to three peripheral stalks and a-subunits. This study not only provides valuable insights into the H-transport mechanism of FF but also opens up possibilities for engineering the foundation of cellular bioenergetics. | |||||||||||||||||||||
