ABSTRACT
The binding of L-[3H]leucine by the plasma membranes from the catfish Ictalurus nebulosus taste organ was studied. The two types of specific binding centers for amino acid with high (KD = 2,5 X 10(-10) M) and low (KD = 1,04 X 10(-9) M) affinities were found. Concentrations of high and low affinity centers were 11,85 nmol/mg and 26 nmol/mg respectively. The structural rearrangement of the surface layer of the chemoreceptor membrane was revealed by spin label technique using 5-doxylstearic acid at leucine concentrations 10(-4)-10(-9) M.
