We will continue a comprehensive and ongoing effort to refine steady-state metabolic network models of these organisms by validating model predictions against many conditions of growth and non- growth for wildtype and knock- out strains.

The EcoCyc Database

EcoCyc includes data imported from the following bioinformatics databases. This chapter provides a detailed description of the data content of EcoCyc, and of the procedures by which this content is generated. Only those annotations that are complete by GO consortium standards are extracted from EcoliWiki; incomplete annotations are left with the hope that community members will eventually complete them. You can help Wikipedia by expanding it.

Only a small subset of the horizontally transferred chromosomal genes in Escherichia coli are translated into proteins. They identified genes that were conditionally essential under these conditions. Network rigidity and metabolic engineering in metabolite overproduction. Skip to search form Skip to main content. Support Center Support Center. EcoCyc is and will continue to be freely and openly available, and is accessible to scientists through the Internet, as downloadable data files, and as a downloadable software application.


Newly identified genetic variations in common Escherichia coli MG stock cultures. Email alerts New issue alert. H7 North American multiple; O EcoCyc is largely up to date with respect to its curation activities.

Examples of imported feature types include catalytic domains, phosphorylation sites, and metal ion binding sites. This study created in-frame, single gene deletion mutants using the lambda RED recombinase system. Distinct paths for basic amino acid export in Escherichia coli: Thus, b-numbers are no longer purely sequential along the genome.

Her efforts created the content for the first organism-scale metabolic database. This dataset consists of growth observations for 95 C compounds under aerobic and anaerobic conditions. All dtabase contain a fully referenced text summary, including when known information on energetics, isoenzyme involvement and the identity of membrane quinone s. Conditioning of uropathogenic Escherichia coli for enhanced colonization of host.

Priority is given to adding new functions for gene products when they are reported in the literature. They also combined these observations with those made by Baba et al [ 42 ] regarding the conditional essentiality of the mutants when grown on glucose supplemented minimal media and were thus able to identify a conserved conditionally essential core of 94 genes that are required for E. To actually run the model, click Execute dtaabase the Results tab. Note that in some cases there were secondary impacts from single-gene deletions, such as compensating suppressor mutations.

The long-term goal of the project is to describe the complete molecular catalog of the E. All transport proteins in EcoCyc are classified within this ontology, making it straightforward for a user to accurately determine the number and identity of proteins within a particular class.


Novel heterologous bacterial system reveals enhanced susceptibility to DNA damage mediated by yqgF, databbase nearly ubiquitous and often essential gene.

This dataset is included in EcoCyc to facilitate benchmarking of computational predictions of ecocc from the EcoCyc model with computations from the model of Feist et al. Prolactin induces lipid synthesis of organ-cultured pigeon crops. The resource and the lessons learned; pp. The chain type is only imported if it does not span the entire length of the protein.

The Supplementary Informationprovided as the accompanying paper-suppl-info. H4 United States. Membrane Transporters EcoCyc annotates E. A staff of four full-time curators updates the annotation of the E.

Note that the inability to obtain an insertion mutant using this system may in some cases be a reflection of the non-targeted nature of transposon insertion rather than a reflection of gene essentiality. Web-based metabolic models are also available for two other gut microbiome organisms in the BioCyc database collection, Bacteroides thetaiotaomicron and Eubacterium rectale.
