Properties of newly synthesized crosslinking reagents (
ACM
) and their applications to proteins are studied (
ACM
is the abbreviation for a series of photoactivable and heterobifunctional crosslinking thiol reagents, each of which has two reactive groups, maleimide and azide). These reagents bind specifically to the sulfhydryl residues of proteins in the first reaction step. Upon photoactivation, the azide group of the coumarin ring reacts with side or main chains of the proteins, and thus intra- or intermolecular crosslinking can be elicited. In addition, the coumarin moiety of the reagents becomes highly fluorescent after photolysis. Therefore, the crosslinking products can be detected by fluorometry with high sensitivity in the pattern of sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Reaction of
ACM
with rabbit muscle
aldolase
led to extensive crosslinking between subunits of the enzyme and maximally 25% of the total subunits were found to be crosslinked to the dimer.
