Provides a library compiling more than 2500 conformational maps of carbohydrate fragments originally described in the CARBBANK. GlycoMapsDB intends to help crystallographers to crosscheck their data before submission as permitted by the Ramachandran plot analysis for proteins. Besides, it can also offers an interface for ‘data mining’ in the Protein Data Bank (PDB) database by finding carbohydrate entries with unusual glycosidic torsion values.
Provides a multistage tandem mass spectral (MS) database using a variety of structurally defined glycans. GMDB offers a resource for glycomics research that enables users to identify glycans by spectral matching. It stores MS2, MS3, and MS4 spectra of N-and O-linked glycans, and glycolipid glycans as well as the partial structures of these glycans.
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.
A comprehensive LC MS/MS library of N- and O- linked glycans released from glycoproteins that have been annotated with glycosidic and cross-ring fragmentation ions, retention times, and associated experimental metadata descriptions.
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.
