1. Sucrase -isomaltase consists of two enzymatic subunits : sucrase and isomaltase.2. Sucrase-isomaltase consists of two enzymatic subunits : sucrase and isomaltase. 3. The crystal structure shows that sucrase -isomaltase exists as a monomer. 4. Sucrase is secreted by the tips of the villi of the epithelium in the small intestine.5. Sucrase -isomaltase is composed of duplicated catalytic domains, N-and C-terminal.6. Invertase is a sucrase used industrially for the hydrolysis of sucrose to so-called invert sugar. 7. Additional digestive enzymes produced by these glands include dipeptidases, maltase, sucrase , lactase, and enterokinase. 8. A deficiency of sucrase may result in malabsorption of sugar, which can lead to potentially serious symptoms. 9. In order to predict isomaltose binding in sucrase -isomaltase structure, a model was produced by hand. 10. Each disaccharide is broken down with the help of a corresponding disaccharidase ( sucrase , lactase, and maltase ).
