N-Terminal sequences of pig intestinal sucrase-isomaltase and pro-sucrase--isomaltase. Implications for the biosynthesis and membrane insertion of pro-sucrase--isomaltase.

The hog sucrase-isomaltase complex is anchored to the small-intestinal brush border membrane, as in the rabbit, via a hydrophobic segment located in the N-terminal region of the isomaltase subunit. The immediate precursor of the 'final' sucrase-isomaltase (i.e.
