8177377-5	1994	SDS-PAGE of hydrophobically labeled DS-AChE revealed the presence of a disulfide bonded hydrophobic membrane anchor of about 20 kDa.	Disulfides	71-80	acetylcholinesterase	Rattus norvegicus	39-43	
7548166-1	1995	Asymmetric acetylcholinesterase (AChE) contains three tetrameric sets of catalytic subunits disulfide-linked to structural subunits of a collagenic tail.	Disulfides	92-101	acetylcholinesterase	Rattus norvegicus	33-37	
1461372-7	1992	These results are compatible with the existence of a hydrophobic segment present both on salt-soluble and detergent-soluble 11 S AChE as well as on the minor forms 4 S and 7 S. This segment is not linked to the catalytic subunits by disulfide bounds in contrast to the 20 kD non-catalytic subunit described by Inestrosa et al.	Disulfides	233-242	acetylcholinesterase	Rattus norvegicus	129-133
