Editing Proteomics (section)

===Protein identification===
Mass spectrometry and microarray produce peptide fragmentation information but do not give identification of specific proteins present in the original sample. Due to the lack of specific protein identification, past researchers were forced to decipher the peptide fragments themselves. However, there are currently programs available for protein identification. These programs take the peptide sequences output from mass spectrometry and microarray and return information about matching or similar proteins. This is done through algorithms implemented by the program which perform alignments with proteins from known databases such as UniProt<ref>{{cite web|url=https://www.uniprot.org/|title=UniProt|website=www.uniprot.org}}</ref> and [[PROSITE]]<ref>{{cite web|url=http://prosite.expasy.org/|title=ExPASy - PROSITE|website=prosite.expasy.org}}</ref> to predict what proteins are in the sample with a degree of certainty.
