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.BiomoleculesQuantitative Methodstext
