The binding of glyceraldehyde-3-phosphate dehydrogenase prepared from rabbit muscle to phospholipid model membranes (liposomes) as a function of pH, ionic strength, and the influence of the binding on specific activity of the enzyme was studied. The binding decreases the specific activity of the enzyme. The binding was studied by the method of association of the enzyme with liposomes during centrifugation. The existence of a dominant interaction of electrostatic character was found.
