Energy landscape of the tautomer states of mesoporphyrin embedded in horseradish peroxidase.

L Herenyi1, J Fidy, J Gafert, J Friedrich.   

Abstract

The energy hypersurface of the dominant tautomer states of mesoporphyrin-substituted horseradish peroxidase was determined by creation of a nonequilibrium population of these states through photochemical transformation at 5 K and measurement of the temperature changes of the respective spectral bands as they were warmed to room temperature.
