ABSTRACT Blocking host cell death is an important virulence strategy employed by many bacterial pathogens. We recently reported that Shigella flexneri inhibits host pyroptosis by delivering a type III secretion system (T3SS) effector OspC3 that catalyzes a novel arginine ADP-riboxanation modification on caspase-4/11. Here. we investigated the OspC3 homologue CopC from Chromobacterium ... https://cosmeticssquadets.shop/product-category/utensils/
