conformational change in rat liver phenylalanine hydroxylase associated with activation by phenylalanine or n- ( 1-anilinonaphth-4-yl ) maleimide was investigated by measuring fluorescence spectra and fluorescence lifetimes of tryptophanyl residues as well as the probe fluorophore conjugated with sh groups of the hydroxylase .
