Identification and characterization of a novel fibronectin-binding protein on the surface of group A streptococci.

ABSTRACT: Understanding the role surface proteins play in the interaction of group A streptococci with epithelial cells is an important step toward the development of new strategies to fight infections. Fibronectin-binding proteins in streptococci and staphylococci have been described as important mediators for adherence to eukaryotic cells. In the present study we describe a new Streptococcus pyogenes fibronectin-binding protein (PFBP). The gene encoding the PFBP protein (pfbp) was identified from an M12 strain genomic library. It encodes a protein of 127.4 kDa which contains the LPXTGX motif characteristic of cell wall-associated proteins in gram-positive organisms and is among the largest surface molecules described for group A streptococci. The pfbp gene is transcribed during cell growth and was
