Expansion of coverage of Carbohydrate Structure Database (CSDB)

•The Carbohydrate Structure Database (CSDB) coverage was expanded.•The Carbohydrate Structure Database now covers bacterial, plant, and fungal glycans.•Plant and fungal glycan data published before 1996 were manually re-annotated.•The data include glycan structures, bibliography, taxonomy, NMR spectra, and others. The Bacterial Carbohydrate Structure Database (BCSDB), which has been maintained since 2005, was expanded to cover glycans from plants and fungi. The current coverage on plant and fungal glycans includes several thousands of the CarbBank records, as well as data published before 1996 but not deposited in CarbBank. Prior to deposition, the data were verified against the original publications and supplemented with additional information, such as NMR spectra. Both the Bacterial and Plant and Fungal Carbohydrate Structure Databases are freely available at http://csdb.glycoscience.ru.
