EcoliHub is a website sponsored by the U.S. National Institutes of Health, trying to bring together researchers interested in Escherichia coli with the most up-to-date information and data. From the EcoliHub site:
Sixty years of study have made Escherichia coli the most deeply understood organism at the molecular level. Much of what we know about cellular processes can be traced to fundamental discoveries in E. coli.
In spite of its great importance as a model organism, information about E. coli is distributed among many online resources. EcoliHub uses web services to make seamless bidirectional connections between E. coli resources, thereby enabling the full use of existing knowledge and supporting cutting-edge research into the molecular basis of life.
