Hypothesis
Why do spherical-shaped chlamydiae harbor MreB, which is typically found in elongated bacteria, while lacking the essential division protein FtsZ?
Conclusion
MreB is involved in directing lipid II biosynthesis to the septum and may be necessary for maintaining a functional divisome machinery in Chlamydiaceae.
Supporting Evidence
- MreB from Chlamydophila pneumoniae polymerizes in vitro.
- MreB interacts with key components in lipid II biosynthesis.
- Polymerization of MreB is favored in the presence of MurF.
- MreB does not require ATP for polymerization.
- A22 does not inhibit the polymerization of chlamydial MreB.
Takeaway
This study looks at a protein called MreB in a type of bacteria that usually doesn't have a cell wall. It finds that MreB helps in making important building blocks for the bacteria's division.
Methodology
The study involved in vitro polymerization assays, co-pelleting assays, and bacterial two-hybrid analysis to investigate MreB's interactions and functionality.
Limitations
The study does not explore the in vivo effects of MreB interactions in the natural environment of Chlamydophila pneumoniae.
