Abstract

The intestinal microvillar enzyme complex sucrase-isomaltase has been studied in cystic fibrosis and control ileum. A number of biochemical parameters of the enzyme in ileum homogenates have been determined. Both solubilized as well as membrane-bound sucrase-isomaltase were analyzed with respect to their reaction with monoclonal antibodies against human sucrase-isomaltase. Finally the subcellular localization of sucrase-isomaltase was verified by immunoelectronmicroscopy or via the analysis of purified brush-border membrane preparations. At all levels no significant differences could be detected between sucrase-isomaltase of cystic fibrosis and control ileum. It is concluded that an abnormal subcellular localization and/or abnormal enzymatic activity of sucrase-isomaltase in cystic fibrosis intestine cannot explain the markedly decreased disaccharidase activities in amniotic fluids from pregnancies resulting in a child affected with cystic fibrosis.
