Surface Analyses and Immune Reactivities of Major Cell Wall-Associated Proteins of Group A Streptococcus

Abstract
A proteomic analysis was undertaken to identify cell wall-associated proteins of Streptococcus pyogenes . Seventy-four distinct cell wall-associated proteins were identified, 66 of which were novel. Thirty-three proteins were immunoreactive with pooled S. pyogenes -reactive human antisera. Biotinylation of the GAS cell surface identified 23 cell wall-associated proteins that are surface exposed.
