Abstract
The small intestinal brush border membrane contains several peptidases and glycosidases of importance for the final digestion of proteins and carbohydrates. These enzymes typically have a main portion in the intestinal lumen and a small N-terminal portion anchoring them to the membrane. Certain maldigestion diseases can be explained by deficient expression of these enzymes. The enzymes are synthesized in the rough e.r.* and transported to the brush border membrane via the Golgi apparatus, where they are modified. Disturbances in these processes may cause depressed enzyme activities; thus sucraseisomaltase is not fully active if incompletely glycosylated.
