The surface-localized M protein, which is the most extensively studied virulence factor of S. pyogenes, has an ∼50-residue N-terminal hypervariable region (HVR) that plays a key role in the escape of the host immunity. Despite the extensive sequence Streptococcus pyogenes is a Gram-positive bacterium that causes several diseases, including acute tonsillitis and toxic shock syndrome. The surface-localized M protein, which is the most extensively studied virulence factor of S. pyogenes, has an ∼50-residue N-terminal hypervariable region (HVR) that plays a key role in the escape of the host immunity.

M protein is a virulence factor that can be produced by certain species of Streptococcus. [1] Viruses, parasites and bacteria are covered in protein and sugar molecules that help them gain entry into a host by counteracting the host's defenses. One such molecule is the M protein produced by certain streptococcal bacteria. The M protein gene (emm) encodes the cell surface M virulence protein responsible for at least 100 Streptococcus pyogenes M serotypes. emm typing is based on sequence analysis of the portion of the emm gene that dictates the M serotype. The hypervariable sequence associated with M serospecificity is adjacent to an amplifying primer sequence Streptococcus pyogenes is a Gram-positive bacterium that causes several diseases, including acute tonsillitis and toxic shock syndrome.

McArthur School of Biological Sciences, University of Wollongong, Wollongong, NSW 2522, Australia. 2008-07-30 · Background Streptococcus iniae is a significant pathogen in finfish aquaculture, though knowledge of virulence determinants is lacking. Through pyrosequencing of the S. iniae genome we have identified two gene homologues to classical surface-anchored streptococcal virulence factors: M-like protein (simA) and C5a peptidase (scpI).

Specific regions of M protein also serve as shared antigens … The M protein gene (emm) encodes the cell surface M virulence protein responsible for at least 100 Streptococcus pyogenes M serotypes. emm typing is based on sequence analysis of the portion of the emm gene that dictates the M serotype. The hypervariable sequence associated with M serospecificity is adjacent to an amplifying primer sequence M protein is a major virulence determinant for the group A streptococcus by virtue of its ability to allow the organism to resist phagocytosis. Common in eucaryotes, the fibrillar coiled-coil design for the M molecule may prove to be a common motif for surface proteins in gram-positive organisms. This type of structure offers the organism several distinct advantages, ranging from antigenic These findings indicate that the structure of the M6 protein is primarily alpha-helical coiled coil. Comparison of the lengths of the fibers on the surface of the streptococcus and the isolated M proteins suggests that each fiber on the cell wall consists of a single M-protein molecule approximately 500 A long. M protein of group A Streptococcus.

M is essential for GAS virulence, providing antiphagocytic functions critical to survival in human tissues Many group A streptococcal strains express two different immunoglobulin-binding proteins, Streptococcal M protein.

Hysmith,a,c,d Thomas A The group A streptococcal M protein virulence factor induces inflammasome activation during infection. Group A Streptococcus (GAS) is among the top ten causes of infection-related mortality in humans. Here we show that streptococcal M protein interacts with TLR2 on human peripheral blood monocytes. As a consequence, monocytes express the cytokines IL-6, IL-1β, and TNF-α.

Direct evidence of this was only provided for GAS strains which expressed a single M protein. secting the immunodominant domains of the M protein, the VV:M6A recombinant appears to be an excellent candidate vaccine for animal trials. Group A streptococcal M protein is a coiled-coil fibrillar molecule found on the surface of the streptococcal cell wall (1, 2) and has the ability to prevent phagocytosis by human phagocytic cells (3). The structural gene for group A streptococcal M protein, the fibrillar surface molecule enabling the organism to resist phagocytosis, has been cloned into Escherichia coli. Se hela listan på academic.oup.com The conformation and molecular dimensions of purified type 6 streptococcal M proteins establish the close structural relationship of these molecules to tropomyosin.
