A Preliminary Work on Evolutionary Identification of Protein Variants and New Proteins on Grids

Protein identification is one of the major task of Proteomics researchers. Protein identification could be resumed by searching the best match between an experimental mass spectrum and proteins from a database. Nevertheless this approach can not be used to identify new proteins or protein variants. In this paper an evolutionary approach is proposed to discover new proteins or protein variants thanks a "de novo sequencing" method. This approach has been experimented on a specific grid called Grid5000 with simulated spectra and also real spectra.
