Streptococcal pyrogenic exotoxin B cleaves GSDMA and triggers pyroptosis. Gavage VS Intraperitoneal VS Intravenous? Cryo-EM structure of the gasdermin A3 membrane pore. Using an air pouch infection model, the wild-type strain NZ131, its isogenic mutants, and complementary mutants were used to examine the effects of SPE B and SLS on GAS . SpeB directly cleaves GSDMA after Gln246. Thus, GSDMA1-246 produced by SpeB cleavage binds and disrupts acidic lipid membranes. Although the proteases that activate GSDMB, C, D and E have been identified, how GSDMA-the dominant gasdermin in the skin-is activated, remains unknown.
