Biology:Streptopain
From HandWiki
Streptopain, also known as streptococcal pyrogenic exotoxin B (SpeB) is a streptococcal cysteine protease.[1][2][3][4] Other names include Streptococcus peptidase A, Streptococcus protease, and streptococcal cysteine proteinase. Streptopain catalyses the following chemical reaction
- Preferential cleavage with hydrophobic residues at P2, P1 and P1'
It is isolated from the group A bacterium Streptococcus pyogenes and acts as a virulence factor.
