[Angiotensin-converting enzyme stability in the presence of zinc-ions different concentrations].
Stability of angiotensin-converting enzyme was studied as a dependence on the zinc-ions concentrations brining in the apo-enzyme. Our data were discussed in the terms of a set of initial permissible conformation conditions of a protein (conformation distribution). Apo-enzyme was shown to be able to the radiation activation that is disappearing in the presence of even 10(-6 )mol/l of the zinc-ions.
