Novel laminin-binding protein of Streptococcus pyogenes, Lbp, is involved in adhesion to epithelial cells.
The lbp gene, which encodes a laminin-binding protein (Lbp) of Streptococcus pyogenes, was found in all S. pyogenes M types. An Lbp-deficient mutant showed a significantly lower efficiency of adhesion to HEp-2 cells than did the wild-type strain. These results indicate that Lbp is one of the important S. pyogenes adhesins.
متن کاملFibronectin binding to a Streptococcus pyogenes strain.
In previous studies, Staphylococcus aureus has been shown to bind fibronectin (P. Kuusela, Nature (London) 276:718-720, 1978), an interaction that may be important in bacterial attachment and opsonization. Recently some strains of streptococci of serological groups A, C, and G were also found to bind fibronectin. The binding to one selected strain of Streptococcus pyogenes has been characterize...
متن کاملThe laminin-binding protein Lbp from Streptococcus pyogenes is a zinc receptor.
The common pathogen Streptococcus pyogenes colonizes the human skin and tonsils and can invade underlying tissues. This requires the adhesion of S. pyogenes to host surface receptors mediated through adhesins. The laminin-binding protein Lbp has been suggested as an adhesin, specific for the human extracellular matrix protein laminin. Sequence alignments, however, indicate a relationship betwee...
متن کاملStreptococcus pyogenes ( Group A Streptococcus )
Group A streptococcus (GAS) is synonymous with Streptococcus pyogenes, the only species within this group of β-hemolytic streptococci. GAS is one of the leading pathogenic bacteria that infects children and adolescents, and is associated with a wide spectrum of infections and disease states. Worldwide, there are estimated to be >600 million cases of GAS pharyngitis (“strep throat”) and >100 mil...
متن کاملIdentification of Rgg binding sites in the Streptococcus pyogenes chromosome.
Streptococcus pyogenes Rgg is a regulatory protein that controls the transcription of 588 genes in strain NZ131 during the post-exponential phase of growth, including the virulence-associated genes encoding the extracellular SpeB protease, pullulanase A (PulA), and two extracellular nucleases (SdaB and Spd-3). Rgg binds to DNA proximally to the speB promoter (PspeB) to activate transcription; h...
