If you are doing protein research, youll eventually need to use protein databases. There lots of them. Querying these databases on the web might take some time and Firefox search engine plugins makes it easier. I found a web site where various search plugins can be found. I found one plugin for Uniprot database and one for PDB but not for "The Biogrid". So Ive generated one for it. You can install it here by clicking on the Biogrid link.
