Photochemical reagents for the study of metalloproteins by flash photolysis

Flash photolysis has been used extensively in the advancement of our understanding of the electron transfer reactivity of metalloproteins and in investigation of the kinetic complexities of electron transfer-initiated protein folding. Additional opportunities for the use of flash photolysis to understand the functional properties of metalloproteins have been afforded through the use of photoactive caged complexes. This review surveys the uses of caged complexes to the study of metalloproteins that have been reported and considers the potential for expanded use of photoactive caged complexes that have not yet been applied in this manner.
