[Chemical characteristics of conformationally-disequilibrium states of metal-containing proteins]

Properties of conformation-out-equilibrium states of several iron containing proteins, for example, induced by fast changes of active site were investigated. It was shown that structure and chemical properties of out-of-equilbrium states can differ considerably from the equilibrium ones. Spectral characteristics and reactional ability of these molecules change in the way of slow (up to 10(-1)s) conformational relaxation, continuously approaching the equilibrium values.
