Amino Acid Sequence; Animals; Antigens, Bacterial/chemistry* Antigens, Bacterial/immunology; Bacterial Outer Membrane Proteins* Bacterial Proteins/chemistry* 2010-06-01 · Whereas much is known about the interaction of PrtF1/SfbI (one of several streptococcal surface 1989-07-01 · 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. The streptococcal Mprotein is now probably one ofthe best-defined molecules of the known bacterial virulence determinants. Its structure, function, immunochemistry,and method of antigenic variation are unique among known virulence molecules and may serve as a model for certain microbial systems.

M protein of group A Streptococcus. Group A Streptococcus (GAS) is a human-specific pathogen, first characterised by Lancefield , which is associated with a wide spectrum of diseases ranging from uncomplicated infections to severe invasive diseases and debilitating sequelae such as rheumatic fever and acute glomerulonephritis .

Streptococcal M protein: alpha-helical coiled-coil structure and arrangement on the cell surface. Phillips GN Jr, Flicker PF, Cohen C, Manjula BN, Fischetti VA. The conformation and molecular dimensions of purified type 6 streptococcal M proteins establish the close structural relationship of these molecules to tropomyosin.

Tobetter appreciate the thinking which The M protein coats group A Streptococci (GAS) and acts as the primary antigen and determinant of type-specific immunity. M is essential for GAS virulence, providing antiphagocytic functions critical to survival in human tissues and fluids. Specific regions of M protein also serve as shared antigens, and Streptococcal M protein and human C4BP Jenny Persson Division of Medical Microbiology Department of Laboratory Medicine Lund University, Sweden LUND 2006 Doktorsexamen i Medicisk Mikrobiologi som med vederbörligt tillstånd från Medicinska Fakulteten vid Lunds Universitet för avläggande 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.

We modelled these in HLA-transgenic mice infected with a clinically lethal isolate expressing Streptococcal pyrogenic exotoxin (Spe) C and demonstrate that both SpeC and streptococcal M protein, acting cooperatively, are required for disease. Oct 15, 2005 Individuals with immunity to M proteins are protected from infection with GAS of the same M protein type.

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
