Abstract
Kinetic and equilibrium studies on the interaction between toluidine blue and poly(αL-glutamic acid) were carried out for both the helical and coiled conformations of polymer. The spectrophotometric measurements show that one bound dye molecule occupies about two and one carboxylic group for the helical and coiled forms, respectively. In the stopped-flow experiments, a relatively fast reaction process was observed for the coiled form, while, a slow process was observed with the helical form. The fast process was attributed to the conformational change of the polymer induced by the dye binding.
