EcoSP (E.coli Surface Polysaccharide) database is an integrated repository of bacterial O-antigens and K-antigens (Escherichia coli) , which collects comprehensive information, including serotypes, and coding region sequences,glycosyltransferases, structures and biosynthetic pathways of K-/O- antigens.
ANTIGENS
There are the lists of all published O-antigens or K antigens, displaying information including the related E. coli strains, the structure (the SPNG, chemical representation with related glycosyltransferases and CSDB test formats) and the synthesis gene cluster of each antigen.
SEARCH
Advanced search provides the queries: the E. coli strain (strain name or genbank accession number), and the serotype.
GLYCOSYLTRANSFERSE
You can search the sugars, glycosidic bonds or the glycosyltransferases for more information, such as the related accepter sugars, the donor sugars, the glycosidic bonds and the enzymes.
PATHWAY
There are all published syntheses pathway of the sugars in the structure of antigens, and all the pathway information including O serotypes, the related strains the key genes in sugar synthesis and the steps of synthesis by searching the sugars.
ANALYSIS
The E. coli genome sequence can be submitted for serotype prediction and glycosyltransferases annotation, and the bacterial sequence can be submitted for just glycosyl transferase prediction.
