More than just K-12 MG1655
More than 500 E. coli strain databases are available via the "Change Current Database" button above. They are less curated than EcoCyc but work with all our website tools, from Omics Dashboard to metabolic route search.
Hazards of the Gut Habitat: Bile
Bile acids are secreted into the intestine, where they promote digestion and absorption of dietary fats. Bile salts are able to diffuse across the inner membrane of E. coli and are cytotoxic. The MdtM antiporter contributes significantly to E. coli's resistance to bile salts, which may represent the natural substrate of this inner membrane transporter.
Cascade to the Rescue!
From protecting E. coli against phage infection to the promise of gene therapy: How does Cascade do it? Recent crystal structures of the enzyme are improving our understanding of this enzyme.
A quantitative metabolic model for E. coli K-12 derived from EcoCyc is available.
Maintaining the Outer Membrane
The 5-subunit Bam complex is responsible for the assembly and insertion of beta-barrel proteins into the OM of E. coli. Although a full understanding of its function in beta-barrel folding remains elusive, recent work has yielded many insights into subunit interaction and activity.

EcoCyc E. coli DatabaseEcoCyc is a scientific database for the bacterium Escherichia coli K-12 MG1655. The EcoCyc project performs literature-based curation of its genome, and of transcriptional regulation, transporters, and metabolic pathways.
EcoCyc is part of the larger BioCyc collection of thousands of Pathway/Genome Databases for sequenced genomes. Click "Change Current Database" above to explore the available databases.
