“With this release, SimGlycan can now analyze glycopeptides in addition to released glycans,” a company release said.

SimGlycan matches the MS/MS spectra with its own comprehensive, robust and annotated database to predict the structure of glycans. It generates a list of all the probable glycans that are close to the experimental data saving time, money and the frustration of laborious work. Each structure is scored to help the user judge which results closely match the experimental data. Alongside the probable glycan structure, important information such as the glycan class, reaction, pathway and enzyme is also made available.

The new version will help users resolve glycan structures in glycopeptide molecules by specifying the sequence or mass of the attached peptide moiety.
