This work is devoted to the study of photolysis of carbonmonoxy myoglobin (MbCO) followed by time resolved circular dichroism (TRCD). Conformational changes that occur in myoglobin are known to play an important physiological role as a model of the trigger of the a! llosteric transformation which takes place in hemoglobin. Upon! ligand dissociation, the heme undergoes an ultrafast doming which propagates along the whole protein through the proximal hisitidine. Experimental measurement of time resolved CD have been carried out in this system. The tricky point was to get rid of the artifact that occurs in such an experiment. A model calculation of CD in myoglobin based on the polarisability theory evidences the key role of the proximal hisiti...
