If you are working with protein sequences, you need GPMAW, a program made by protein chemists for protein chemists. Although the program has been designed as a daily tool for mass spectrometric analysis, all protein chemists who work with sequences this a program like this to handle their structures and provide basic analysis. The main design goals of the program have been ease-of-use without sacrificing speed and precision. Protein sequences can easily be imported and edited from a number of sources, i.e. direct searches in databases or copied from the internet or other programs. Multiple sequences can be loaded simultaneously, highlighted, colored, displayed in 1- or 3-letter code and cleaved by enzymes or by user specifications. The program also handles multiple chains, cross-links and modified amino acid residues. All proteins and peptides are reported along with a number of physical/chemical characteristics like precise mass (average and monoisotopic, singly and multiply charged), pI, absorption, charge, HPLC index etc.

Databases can be searched locally for digest masses, proteins for compositions, graphs can be displayed for hydrophobicity, secondary structure prediction, theoretical HPLC peptide chromatogram, databases as 2D gels etc. 

NOW includes the entire Swiss-Prot and EMBL Databases....over 800,000 proteins!
