Abstract
Pepsin-resistant fragments of the tail subunits of 14 and 18 S acetylcholinesterases from eel electric organ were composed of three 24,000-molecular weight polypeptides linked by intersubunit disulfide bonds in a collagen-like triple helix. Intact tail subunits appeared to contain both the triple-helical domain and a noncollagenous domain that is linked to catalytic subunits by disulfide bonds. Structural relations among the pepsin-resistant fragments of 14 and 18 S acetylcholinesterase are considered.
