Proteomics, assisted by mass spectrometry, is a powerful method to identify cell wall proteins. Given that mass spectrometry can go beyond the bounds of protein identification to explore protein structure, an in-depth analysis can be done on mass spectrometry data. Such data permit to uncover maturation events by site mapping or to detect post-translational modifications. ProTerNyc was developed as a bioinformatic tool to predict the location of the N-terminus of mature secreted proteins and N-glycosylated peptides using the data obtained by mass spectrometry.
