16286459-4	2006	Cleavage of VWF by recombinant ADAMTS13 was activated up to approximately 200-fold by zinc ions (K(D) (app) approximately 0.5 microM), calcium ions (K(D) (app) approximately 4.8 microM), and barium ions (K(D) (app) approximately 1.7 mM).	Barium	191-197	ADAM metallopeptidase with thrombospondin type 1 motif 13	Homo sapiens	31-39	
16286459-5	2006	Barium ions stimulated ADAMTS13 activity in citrated plasma but not in citrate-free plasma.	Barium	0-6	ADAM metallopeptidase with thrombospondin type 1 motif 13	Homo sapiens	23-31	
16286459-6	2006	Therefore, the stimulation by barium ions of ADAMTS13 in citrated plasma appears to reflect the release of chelated calcium and zinc ions from complexes with citrate.	Barium	30-36	ADAM metallopeptidase with thrombospondin type 1 motif 13	Homo sapiens	45-53
