Damage to erythrocyte membranes by botulinolysin (BLY) was studied by
electron microscopy, which revealed ring-shaped structures with inner
diameters and widths of approximately 32 and 6.7 nm, respectively. BLY
bound to membranes at 0 degrees C, but subsequent treatment with glut
araldehyde prevented ring formation during further incubation at 37 de
grees C. Zn2+ ions inhibited ring formation but not binding of BLY to
membranes.
