MetaNetX

MetaNetX is a comprehensive resource for metabolic network reconstruction and analysis. It functions as a large, integrated database of biochemical reactions and metabolites, drawn from various public sources and harmonized into a consistent and standardized format. The primary goal of MetaNetX is to provide a unified platform that facilitates the comparison and integration of different metabolic models and datasets.

MetaNetX achieves interoperability through a number of key features:

• Unified Identifiers: MetaNetX assigns unique identifiers to metabolites and reactions, resolving inconsistencies and redundancies present in different databases. This allows for unambiguous referencing of biochemical entities across different models and datasets.

• Cross-Referencing: The database provides extensive cross-references to other relevant databases, such as KEGG, ChEBI, Rhea, and BiGG Models. This allows users to easily navigate between MetaNetX and other resources to obtain additional information.

• Reaction Balancing and Stoichiometry: MetaNetX ensures that all reactions are mass and charge-balanced, and provides consistent stoichiometric coefficients. This is crucial for accurate modeling and simulation of metabolic networks.

• Compartmentalization Information: MetaNetX includes information on the subcellular localization of metabolites and reactions, enabling the reconstruction of compartment-specific metabolic models.

• Network Topology: The database provides information on the connections between metabolites and reactions, allowing for the analysis of network topology and the identification of key metabolic pathways.

MetaNetX is primarily used by researchers in the fields of systems biology, metabolic engineering, and bioinformatics. It supports a variety of applications, including:

• Metabolic Model Reconstruction: MetaNetX provides the necessary information to build and refine genome-scale metabolic models.

• Metabolic Pathway Analysis: MetaNetX allows for the identification and analysis of metabolic pathways involved in specific biological processes.

• Metabolic Flux Analysis: The consistent reaction stoichiometries and network topology in MetaNetX facilitate the simulation of metabolic fluxes under different conditions.

• Comparative Genomics: MetaNetX can be used to compare the metabolic capabilities of different organisms.

• Drug Target Identification: By analyzing metabolic networks, researchers can identify potential drug targets.

MetaNetX is a continually updated and maintained resource. Its reliance on community feedback and contributions ensures that it remains a valuable tool for researchers studying metabolism.
