About EcoCyc

EcoCyc is a database of literature-based "gold standard" annotation of the molecular components of E. coli K-12, primarily referencing strain MG1655. EcoCyc is a central part of the BioCyc collection of database at SRI International in Menlo Park, CA.

Using EcoCyc

Searching

When the input is a gene or protein:

This db tells you practically everything you ever wanted to know about a gene or protein. When you insert the query, the output allows a decision between the gene or its protein product. Most of the information is in the form of links. In fact, 90% of the page is link-able, which could get messy if you don't quite know what you are looking for. The information in EcoCyc is also referenced, with the bibliography at the bottom of the linked page.

To get a sequence to enter into your Cloning software:

If you need the gene (start to stop codons) or protein sequence, click on the appropriate tab at the very top of the page. There is also a page that allows you to specify what range of DNA you want. To get back to the parC page, click the Back button of your browser. Very simple.

To see what genes flank your gene of interest:

Click on the genome browser link at the map position heading (4th heading down the page). You may see what flanks your gene as well as directionality. This tool resembles Google MapsTM, in that it has arrows that allow you to move along the gene map in either direction. To get back to the previous page, just click the Back button of your browser.
