OS BACILLUS ANTHRACIS. OG PLASMID PXO1. OC PROKARYOTA; FIRMICUTES; ENDOSPORE-FORMING RODS AND COCCI; BACILLACEAE. RN [1] (SEQUENCE FROM N.A.) RA WELKOS S.L., LOWE J.R., EDEN-MCCUTCHAN F., VODKIN M., LEPPLA S.H., RA SCHMIDT J.J.; RL GENE 69:287-300(1988). CC -!- FUNCTION: PA IS ONE OF THREE PROTEINS COMPRISING ANTHRAX TOXIN. CC THE THREE PROTEINS ALONE ARE NONTOXIC. PA INDUCES IMMUNITY TO CC INFECTION. THE LETHAL TOXIN, WHICH CONTAINS PA AND LF, CAUSES CC DEATH IN RATS, GUINEA PIGS AND RABBITS. CC -!- PA MUST BIND A CELLULAR RECEPTOR AND BE ACTIVATED BY PROTEOLYTIC CC CLEAVAGE, IN ORDER TO PERMIT THE COMPETITIVE BINDING OF LF AND EF CC TO PA. THE ENTIRE TOXIN COMPLEX ENTERS THE CELL BY ENDOCYTOSIS.
