Submission of a rat liver homogenate made in 250 mM sucrose-1 mM EDTA to centrifugation between 9,500 times g for 10 min and 105,000 times g for 60 min results in the sedimentation of 60 to 70% of the total cellular fructose 1,6-bisphosphate aldolase (EC 4.1.2.13). Under these conditions only about one-quarter of the total triose phosphate dehydrogenase and phosphoglycerate kinase appears in the microsomal fraction. Ultrastructural immunologic localization techniques have demonstrated that the aldolase is associated with the endoplasmic reticulum, in situ. The binding of this enzyme to the membrane is sensitive to changes in pH with an optimum at 6.0, and to increasing concentrations of NaCl and fructose 1,6-bisphosphate, being about 100-fold more sensitive to the ester than to the inorganic salt.
