  In regular proteomics approaches proteases are used to digest the proteome into a set of peptides. Unfortunately, determining proteins on the basis of peptides implies some uncertainty since a peptide may be part of different proteins. Therefore, a targeted detection of unique peptides of particular proteins is a promising task for an unambiguous identification of a specific protein. Here we present a software solution that offers the possibility for a highly efficient and simple detection of such unique peptides. In a first step a SQL-based database of theoretically digested peptides from a given FASTA file formatted protein database is generated by choosing a protease. In a second step, in silico generated peptides from a pre-defined protein sequence are compared to this peptide database in order to identify unique peptides. Amongst others, possible.. View More»
