A bioactive polypeptide from sugarcane selectively inhibits intestinal sucrase

Human sucrase enzyme is a key therapeutic target for type 2 diabetes. While sugarcane sucrase inhibitor (sucinh) modulates invertase activity thereby accumulates sucrose. Molecular level understanding of sucinh towards mammalian α-glucosidases is scarce. The interaction of sucinh with human sucrase was identified and the association of these proteins was confirmed using co-purification, co-immunoprecipitation and pull-down assay. In addition,...
