Abstract:
SPAC (sequence protein alignment with composition) is a software that retrieve from protein or nucleic acid databases, the sequences corresponding to a protein or peptide whose only amino acid composition and molecular weight are known. By accurately matching a DNA or a protein sequence to candidate protein or peptide fragment, this software may be used as a fast and cheap method for protein characterization. This paper describes a modification of the SPAC software, SPAC new evolutions (SPACne), which enables a more efficient and user friendly method of protein identification using amino acids composition. SPACne is available online at the web site: http://bioweb.pasteur.fr/seqanal/interfaces/spacne.html.
