Answer:
The correct answer will be option- <em>Streptococcus pyogenes.</em>
Explanation:
M protein is an important virulence factor which is produced and expressed on the surface of <em>Streptococcus pyogenes.
</em>
This protein plays important role in the bacterial infection like adherence to epidermal keratinocytes, resistance to phagocytosis, invasion of epithelial cells and microcolony formation.
The M-protein is a α-helical coiled structure protein which consists of the four distinct regions (A–D) in which A-region in the N-terminal is highly variable.
Thus, option- <em>Streptococcus pyogenes</em> is the correct answer.
