PolysacDB ID | 2386 |
Carbohydrate Name | Streptococcal polysaccharide antigen eI (Drugpedia) |
Carbohydrate Class | Capsular polysaccharide |
Microbe Name | Streptococcus mutans strain MT703 serotype e (NCBI Taxonomy) (Drugpedia) |
Basic Structure | The major fraction (eI) was identified as a polysaccharide composed of 37% glucose, 56% rhamnose, 5% protein, and 0.3% phosphorus, whereas the minor fraction (eII) contained 66% protein in addition to 10% glucose and 17% rhamnose

BCSDB Structure | N/A |
Proposed Function | N/A |
Antigenic Nature | Whole cells |
Carrier Name | Nil |
Conjugate Method | Nil |
Antibodies | Antisera |
Antibody Type Class | N/A |
Assay System | Quantitative precipitin test and immunodiffusion and/or immunoelectrophoresis |
Cross Reactivity | This antisera cross-reacted with type E |
Proposed Epitope | Methyl-β-D-glucopyranoside residues seemed to be the predominant epitope. A β-linked glucose-glucose dimer is the predominant antigenic determinant of the e specificity |
IEDB Epitope | N/A |
Proposed Utility | This antisera may help in elucidating the antigenic specificity of E and e antigens on the surface of streptococcus mutans |
