MetaNetX.org allows to access, analyse and manipulate genome-scale metabolic networks as well as biochemical pathways. It consistently integrates data from various public resources and makes the data accessible in a standardized format using a common namespace. Models can be interactively compared, analysed (e.g. detection of dead-end metabolites/reactions, flux balance analysis or simulation of reaction/gene knockouts), manipulated and exported. Users can upload their own metabolic models.
The Protein Model Portal has been developed to foster effective usage of molecular models in biomedical research by providing convenient and comprehensive access to structural information for a protein - both experimental structures and theoretical models. Protein Model Portal is a component of the Nature PSI Structural Biology Knowledgebase.
