The following is an examples of searching the METATRYP Coronavirus database with a complete surface glycoprotein sequence from SARS-CoV-2 (NCBI accession YP_009724390.1). The METATRYP search will "digest" the protein sequence into its component tryptic peptides, and then search the database for each peptide.
