Hypothesis
What is the prevalence and role of phosphorylation in Mycoplasma genitalium and Mycoplasma pneumoniae?
Conclusion
Phosphorylation in mycoplasmas is comparable to that of other bacterial species and may play a significant role in cellular processes.
Supporting Evidence
- 24 distinct phosphoproteins were identified in the mycoplasmas.
- 58% of the identified phosphoproteins were associated with a cytoskeleton-like structure.
- Phosphorylation levels were compared between exponential and stationary growth phases.
Takeaway
The study found that mycoplasmas have many proteins that are modified by phosphorylation, which helps them function properly.
Methodology
The study used two-dimensional gel electrophoresis and mass spectrometry to identify phosphorylated proteins in mycoplasmas.
Limitations
The phosphorylation patterns might be altered from wild-type due to the attenuated strain used.
