7506232-5	1993	Human alpha 2M contains an internal thiol ester and the disulphide bridged dimer of the complex appears to be the functional unit of alpha 2M.	disulphide	56-66	alpha-2-macroglobulin	Homo sapiens	6-14	
7516153-3	1994	A small amount of bLPL was bound covalently to alpha 2M by disulphide interchange, when incubated together with chymotrypsin or methylamine.	disulphide	59-69	alpha-2-macroglobulin	Homo sapiens	47-55	
7506232-5	1993	Human alpha 2M contains an internal thiol ester and the disulphide bridged dimer of the complex appears to be the functional unit of alpha 2M.	disulphide	56-66	alpha-2-macroglobulin	Homo sapiens	133-141	
6169340-9	1980	It was deduced that PAPP-A, like alpha 2M, is a dinner, whose protomers are composed of disulphide-linked polypeptide chains.	disulphide	88-98	alpha-2-macroglobulin	Homo sapiens	33-41	
91367-8	1979	Electrophoresis of S-alpha 2M in the presence of sodium dodecylsulphate gave results consistent with the view that the alpha 2M molecule is a tetramer of identical subunits, assembled as a non-covalent pair of disulphide-linked dimers.	disulphide	210-220	alpha-2-macroglobulin	Homo sapiens	119-127	
91367-15	1979	Exposure of S-alpha 2M to 3 M-urea or pH3 resulted in dissociation to the disulphide-bonded half-molecules; these did not show the proteinase-binding activity characteristic of the intact alpha 2M.	disulphide	74-84	alpha-2-macroglobulin	Homo sapiens	14-22	
91367-19	1979	F-alpha 2M formed by reaction with a proteinase or ammonium salts was not dissociated under the same conditions, although the interchain disulphide bonds were reduced.	disulphide	137-147	alpha-2-macroglobulin	Homo sapiens	2-10
