Hypothesis
Does SycO play a regulatory role in the type III secretion system of Yersinia enterocolitica?
Conclusion
SycO is integrated into the regulatory network of the Yersinia type III secretion system and interacts with YscM1.
Supporting Evidence
- SycO forms homodimers, which is typical for chaperones.
- Overproduction of SycO decreases secretion of Yops into the culture supernatant.
- SycO interacts with YscM1, a negative regulator of Yop expression.
Takeaway
SycO is a protein that helps control how Yersinia bacteria release harmful substances, and it works with another protein called YscM1.
Methodology
Recombinant production of SycO was performed in E. coli, followed by purification and analysis of its interactions and effects on Yop secretion.
