title: Tryptic digestion of native small-intestinal sucrase - isomaltase complex: isolation of the sucrase subunit.
abstract: Limited tryptic digestion of native sucrase - isomaltase complex produced a more rapid destruction of isomaltase activity than sucrase activity. It was possible to isolate a partially fragmented sucrase subunits in high yields with a specific activity twice that of the native complex. Amino acid and carbohydrate analyses are reported and compared with the results obtained for sucrase - isomaltase complex and isomaltase subunit obtained by a different method.
