title: 19F NMR characterization of the thermodynamics and dynamics of the acid-alkaline transition in a reconstituted sperm whale metmyoglobin.
abstract: A 19F NMR study on the acid-alkaline transition in sperm whale myoglobin reconstituted with a perfluoromethyl heme, 13,17-bis(2-carboxylatoethyl)-3,8-diethyl-2,12,18-trimethyl-7-trifluoromethylporphyrinatoiron(III), demonstrated that the thermodynamics of the transition is predominantly controlled by the stability of acidic form.
