Hypothesis
Subunit c of ATP synthase can encapsulate water, potentially aiding early complex chemistry.
Conclusion
The study shows that subunit c of ATP synthase can change its structure to encapsulate water, which may have been crucial for early biochemical processes.
Supporting Evidence
- Subunit c can change its hydrogen bonding structure to encapsulate water.
- The protein can retain water over a temperature rise from 123 to 223 K.
- The encapsulated water forms highly ordered hexagonal crystals.
Takeaway
A special protein can wrap around water like a balloon, which might have helped life start a long time ago.
Methodology
The study involved mixing purified subunit c with water and observing the formation of vesicles and tubes using microscopy techniques.
Limitations
The study primarily focuses on a specific protein and its interactions with water, which may not represent all proteins or conditions.
