| 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 |
