Hypothesis
Can microseeding improve the crystallization of proteins complexed with hydrolyzable substrates?
Conclusion
Microseeding significantly accelerates the crystallization of ChoX with acetylcholine, allowing for successful structure determination within 24 hours.
Supporting Evidence
- Microseeding allowed for the crystallization of ChoX with acetylcholine in under 24 hours.
- Crystals produced by microseeding showed high quality and diffraction up to 1.8 Å.
- The study highlights the advantages of microseeding in overcoming hydrolysis issues during crystallization.
Takeaway
Scientists found a way to make protein crystals grow faster by using tiny seed crystals, which helps prevent the proteins from breaking down.
Methodology
The study used a microseeding method to induce rapid crystal formation of ChoX complexed with acetylcholine.
Limitations
Crystals obtained through microseeding exhibited a high twinning fraction, which may complicate data analysis.
