Species‐specific binding of human secretory component to SpsA protein of Streptococcus pneumoniae via a hexapeptide motif
1 May 2000
Abstract excerpt
SpsA, a pneumococcal surface protein belonging to the family of choline-binding proteins, interacts specifically with secretory immunglobulin A (SIgA) via the secretory component (SC). SIgA and free SC from mouse, rat, rabbit and guinea-pig failed to interact with SpsA indicating species-specific binding to human SIgA and SC. SpsA is the only pneumococcal receptor molecule for SIgA and SC as confirmed by complete...
