Coding sequence for Aerolysin

Secreted, cytolytic toxin that forms pores in host membranes after proteolytic removal of a C-terminal propeptide, leading to destruction of the membrane permeability barrier and host cell death. The pores are formed by transmembrane beta-strands and are approximately 3 nm in diameter. This part has been codon optimized for expression in Escherichia coli. The composite part BBa_K4323001 includes the necessary components to express Aerolysin toxin. For more information, please visit our Wiki page.
