Abstract

Previous picosecond laser experiments aimed at detecting rapid processes in hemeproteins have involved studying changes in the heme electronic structure as a result of electronic excitation or photodeligation of CO [1–6], O2 [1 ,4–6] and NO [6,7]. Recent femtosecond studies of these systems are reported elsewhere in this book [8]. A goal of the present research is to pave the way for the study of the conversion of such electronic and chemical changes into conformational changes throughout the protein. As a first step we have attempted in the present work to study the picosecond anatomy of the tryptophans in myoglobin.
