The interactions between SudanⅡ and Myoglobin(Mb) were investigated via fluorescence spectro-scopy.The experimental results suggest that there is strong interaction between SudanⅡ and Mb.The binding site number n is about 1 and the binding constant,K,is 3.84×107 L/mol.The position,type and energy of the interaction between SudanⅡ and Mb were investigated by means of the flexible molecule docking technology.It was obtained from the theoretical calculation that the values of potential energy,electrostatic energy and van der waals energy of the interaction between SudanⅡ and Mb are-9 419.9,-7 468.8,-1 951.0 kJ/mol,respectively.SudanⅡ can form hydrogen bonds with His64 of Mb.In addition,SudanⅡ can interact with Phe33,Phe43,Phe106 and Phe138 residues,which can produce fluorescence.Thus,the interaction can lead to the fluorescence quenching of Mb.This is in good agreement with the result of the fluorescence experiment.
