摘要: Anthrax lethal toxin, produced by the bacterium Bacillus anthracis, is major cause of death in animals infected with anthrax. One component this factor (LF), suspected to be a metalloprotease, but no physiological substrates have been identified. Here it shown that LF protease cleaves amino terminus mitogen-activated protein kinase kinases 1 and 2 (MAPKK1 MAPKK2) cleavage inactivates MAPKK1 inhibits MAPK signal transduction pathway. The identification site for may facilitate development inhibitors.
