Carbohydrate Name
Streptococcal polysaccharide antigen eI
Carbohydrate Class
Miscellaneous
Source Microbe
Streptococcus mutans strain MT703 serotype e
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
Proposed functions

Antibodies
Antisera
Antibody type and class
N/A
Assay System
Quantitative precipitin test and immunodiffusion and/or immunoelectrophoresis
Cross-reactivity
This antisera cross-reacted with type E
Proposed epitopes
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
Proposed Utility
This antisera may help in elucidating the antigenic specificity of E and e antigens on the surface of streptococcus mutans
