Hypothesis

What is the relationship between extreme pathways and correlated reaction sets in metabolic networks?

Conclusion

Extreme pathways and correlated reaction sets are strongly related, suggesting a regulatory mechanism in metabolic networks.

Supporting Evidence

  • Extreme pathways cover correlated reaction sets in an 'all or none' manner.
  • Correlated reaction sets are identified for E. coli and red blood cell metabolic networks.
  • Sampling was used to analyze the large-scale Saccharomyces cerevisiae metabolic network.

Takeaway

This study looks at how different pathways in cells work together. It finds that some pathways either use all reactions or none at all, which helps cells survive.

Methodology

The study used constraint-based modeling and uniform random sampling to analyze metabolic networks.

Limitations

The study may not cover all possible extreme pathways due to the computational complexity of large networks.
