Abstract

Our previous studies showed that β-(±)-2-aminobicyclo-(2.2.1)-heptane-2-carboxylic acid (BCH), a synthetic and non-metabolizable amino acid, stimulates liver glutaminase in intact mitochondria and isolated hepatocytes (Zaleski et al., 1986a,b). Since the effect on glutaminase, a protein associated with the inner mitochondrial membrane (McGivan et al., 1980), required preservation of mitochondrial integrity, it was proposed that not the enzyme itself but the membrane is a primary target for BCH action. It has, furthermore, been suggested that interactions between glutaminase and the mitochondrial membrane are controlled by mitochondrial metabolism (Zaleski et al., 1986b).
