Conclusions
-
1.
The fluorescence of acridine in aqueous medium and in a number of organic solvents, as well as that of acridine bound in the adsorption site of α-chymotrypsin, was studied.
-
2.
Acridine bound to α-chymotrypsin is in contact with proton donor groups in the hydrogen bond, possessing reduced proton donor properties.
-
3.
Complexes of α-chymotrypsin and acridine, formed in aqueous medium and in anhydrous DMSO, possess close fluorescent properties.
