Elsewhere, in the two-component hemolysin system of
Pleurotus ostreatus, pleurotolysin A and B form pores of 3.8 – 5 nm in size [43].
Flammutoxin has been reported to form pores of at least two different sizes [44].
Collectively, these sizes reported in these studies are smaller than those typically observed
for other β-pore-forming toxins (15 – 30 nm) and CDCs (350 – 500 nm)
