Modification of some properties of spherical lipid membranes induced by the association with fructose-1,6-bisphosphate aldolase

The influence of fructose-1,6-bisphosphate aldolase, as a membrane peripheral protein, on some electrical and transport properties of spherical lipid membranes was investigated. It was found that the association of the enzyme with the membrane did not effect markedly the electrical conductance or capacity of the membrane but decreased the water filtration coefficient and the cationic transferance number. The enzyme association also modifies temperature characteristics of the membrane parameters.
