Genome-Based Peptide Fingerprint Scanning
Encyclopedia
Genome-based peptide fingerprint scanning (GFS) is a system in bioinformatics
analysis that attempts to identify the genomic origin (that is, what species they come from) of sample protein
s by scanning their peptide-mass fingerprint
against the theoretical translation and proteolytic digest of an entire genome.
Bioinformatics
Bioinformatics is the application of computer science and information technology to the field of biology and medicine. Bioinformatics deals with algorithms, databases and information systems, web technologies, artificial intelligence and soft computing, information and computation theory, software...

Protein
Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

Peptide-mass fingerprint
In bio-informatics, a peptide-mass fingerprint or peptide-mass map is a mass spectrum of a mixture of peptides that comes from a digested protein being analyzed. The mass spectrum serves as a fingerprint in the sense that it is a pattern that can serve to identify the protein....
