The interactions of angiotensin II and a synthetic analogue, [As&, Val"] angiotensin I!. with Ca2+ and Tb3+ have been monitored using the intrinsic fluorescence of the tyrosine residue at position 4 in both molecules. The data indicate that angiotensin II binds both metals with a dissociation consta
