The M protein, the most well-characterised GAS virulence determinant, is a surface expressed coiled coil protein that extends up to 60 nm from the cell wall (Phillips et al. 1981;McNamara et al.

Shangwei Wu, in Molecular Medical Microbiology (Second Edition), 2015. M Protein-Mediated Invasion. M protein is an important virulence factor expressed on the surface of S. pyogenes and plays multiple roles in streptococcal infection, including resistance to phagocytosis, adherence to epidermal keratinocytes, microcolony formation and invasion of epithelial cells [192].

M protein, or actually "protein M," is relevant to the bacterium mycoplasma genitalia. Isolated complement components were used to study the regulation of the alternative complement pathway C3 convertase (EC 3.4.21.47), also called C3b,Bb, on M protein-carrying (M+) and M protein-lacking (M-) streptococci. Neither M- nor M+ streptococci directly affected the formation or dissociation of the surface-bound C3b,Bb or the inactivation of surface-bound C3b by factor I.

The aim of this thesis is to further elucidate the immunomodulatory role of platelets activated by streptococcal M proteins. STREPTOCOCCAL M PROTEIN EXTRACTED BY NONIONIC DETERGENT II. Analysis of the Antibody Response to the Multiple Antigenic Determinants of the M-Protein Molecule* BY VINCENT A. FISCHETTI~ (From The Rockefeller University, New York 10021) Streptococcal M proteins are antiphagocytic molecules varying immunologi- Streptococcal M protein, the antiphagocytic molecule on the surface of the organism, was previously found to exhibit extensive size heterogeneity between as well as within M serotypes. Although it is well established that the streptococcal M protein extends from the surface of the streptococcal cell as an alpha-helical coiled-coil dimer with structural homology to myosin and other alpha-helical coiled-coil molecules (16, 17), no studies have investigated the role of M protein in an animal model of valvular heart disease, the most serious sequela of RF.

A resurgence of invasive streptococcal diseases and rheumatic fever has appeared in outbreaks over the past 10 years, with a predominant M1 serotype as well as others identified with the outbreaks. emm (M protein) gene sequencing has changed serotyping, and new virulence genes and new virulence regulatory networks have been defined.

[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.

The major virulence factor of S. pyogenes is the M protein, a fibrillar surface protein that prevents phagocytosis and contributes to virulence also
