Finds reliably glycopeptides from a few thousand collected tandem mass spectrometry (MS/MS) spectra. The GlyDB approach was developed for annotation of low resolution spectra generated by ion trap mass spectra. In the case of simple structures, such as bi-antennary glycans, GlyDB can provide direct assignment. And in the case of more complex glycan structures, it typically selects several potential candidate structures, but in order to assign the most likely structure, additional experiments may be required.


Incorporates mass spectrometry experiment data from disparate sources. Then, it can organize them into a uniformed format for users to share. GlycomicsDB offers the possibility for collaborating researchers to access and manage the shared glycomics data in a systematic manner within a single resource. It can handle raw mass spectral data and glycan structures in a systematic and integrated way and it provides a user-friendly interface to create, edit and manage glycan structures as 3D models as well as 2D diagrams.
