Intracellular M protein of group A Streptococcus. J. Bacteriol. 85:536–540. 1963.—A heat-labile M protein antigen in protoplasts of a type 14 strain of group A Streptococcus has been demonstrated in a soluble form in the cytoplasm, and also bound

Group A streptococcus (GAS) is known to cause a broad spectrum of illness, from pharyngitis and impetigo, to autoimmune sequelae such as rheumatic heart 

Monoclonal antibodies 7A7C6 (anti-Szp) and 4E2F8 (anti-M-protein) were evaluated for their specificity against the stimulating antigen using Western Blot assays and titered by ELISA. 6398 HAANESANDCLEARY MATERIALSANDMETHODS Bacterial strains. S. pyogenes CS101 was the source of DNAused in cloning the M49gene. Strain CS103 (27), an M-negative, OF-negative variant ofCS101, wasused as an absorbent and as a negative control in serological experi- ments. 2018-03-04 The M protein is an alpha-helical coiled-coil dimer extending from the surface of the bacteria as a fibril . Its structure is divided into conserved, central variable, and N-terminal hypervariable regions .

La clave del poder de la  8 Jul 2019 Plasminogen (Plg)-binding M protein (PAM) is a group A streptococcal cell surface receptor that is crucial for bacterial virulence.

Streptococcus pyogenes causes a variety of infections because of virulence factors such as capsular hyaluronic acid and M protein.

M protein is an abnormal protein caused by plasma cells.

Here we demonstrate that M protein, a major surface-expressed virulence factor of the human bacterial pathogen, Streptococcus pyogenes, mediates binding to various forms of GAGs. Streptococcus pyogenes är en viktig bakteriell patogen som ger upphov till bl.a. halsfluss och svinkoppor hos människor. Alla S. pyogenes-stammar uttrycker det s.k. M-proteinet på sin yta.

Briefly, 1 mL of each purified recombinant protein (1.6 mg M protein or 2.5 mg SLO toxoid) was mixed 1:1 with the adjuvant Montanide ISA 50 (Seppic Inc; Fairfield, New Jersey). Several microbial pathogens have been reported to interact with glycosaminoglycans (GAGs) on cell surfaces and in the extracellular matrix.
