Donald Hunt has made seminal contributions to the fields of proteomics, immunology, epigenetics, and glycobiology. The foundation of every important work to come out of the Hunt Laboratory is de novopeptide sequencing. For decades, he taught hundreds of students, postdocs, engineers, and scientists to directly interpret mass spectral data. To honor his legacy and ensure that the art of de novosequencing is not lost, we have adapted his teaching materials into “The Hunt Lab Guide to De NovoPeptide Sequence Analysis by Tandem Mass Spectrometry”. In addition to the de novosequencing tutorials, we present two freely available software tools that facilitate manual interpretation of mass spectra and validation of search results. The first, “Hunt Lab Peptide Fragment Calculator”, calculates precursor and fragment mass-to-charge ratios for any peptide. The second program, “Predator Protein Fragment Calculator”, was inspired in part by the fragment calculator developed in the Hunt Lab. Its capabilities are enhanced to facilitate interpretation of mass spectral data derived from intact proteins. We hope that the combination of these educational tools will continue to benefit students and researchers by empowering them to interpret data on their own. |
