126576-2	1975	An active C3 cleaving enzyme is generated when properdin factor B (glycine-rich beta-glycoprotein, GBG) is activated (GBG is cleaved) by factor D in the presence of C3b and Mg++.	Magnesium	173-177	complement factor B	Homo sapiens	47-65	
126576-9	1975	C3 was activated and the resulting C3b fragment fixed on agarose by incubating C3 with trypsin covalently bound to the agarose.	Sepharose	57-64	complement C3	Homo sapiens	35-38

126576-10	1975	The agarose-C3b intermediate was capable of binding GBG provided Mg++ was present.	Sepharose	4-11	complement C3	Homo sapiens	12-15	
126576-10	1975	The agarose-C3b intermediate was capable of binding GBG provided Mg++ was present.	Magnesium	65-69	complement C3	Homo sapiens	12-15	
126576-16	1975	C3b and CVF act in the same way, they form a reversible, weakly active C3 cleaving complex with GBG and Mg++, the activity of which is markedly enhanced but becomes subject to decay when GBG is cleaved by trypsin-like enzymes while bound to CVF or C3b.
