Using Proteome analysis databases for molecular phylogeny

The Proteome Analysis Databases (PAD) (http://www.ebi.ac.uk/proteome/) is a very useful tool for giving simultaneously the key representative proteomes of archean and bacterium as well as three eukaryotic kingdoms, i.e., animal, plant and fungus. Moreover, it integrates the information of higher structures of proteins interested. This paper introduces the structure and function of Proteome Analysis, then our study on the erythrocruorin with the Proteome Analysis, finally, a few interested results obtained even though it is rather preliminary.
