Entrez Results

Take note of the DEFINITION, SOURCE and ORGANISM, AUTHORS of the sequence, and the TITLE and JOURNAL name of the article published about it. If you don’t already have this article, you can retrieve it simply by clicking on the PUBMED number (in the live window) and print the PDF version. Then find your way back to the results page.

Skip down through the FEATURES and note the ORIGIN section, which gives you the amino acid sequence of your protein. This is the sequence we’ll use in a BLAST search, but the default format is not particularly helpful. Click NEXT on the tutorial to examine another feature of the NCBI page.
