ABSTRACT Many Gram-negative bacterial symbionts and pathogens employ a type III secretion system (T3SS) to live in contact with eukaryotic cells. Because T3SSs inject bacterial proteins (effectors) directly into host cells. the switching of secretory substrates between translocators and effectors in response to host cell attachment is a crucial step for the effective delivery of effec... https://pipingrockers.shop/product-category/antioxidants/
