Page 3 2) 7. J a) Glucosidase I catalyzes hydrolysis of specific glucosidase I is a synthetic trisaccharide, glucose-al-2- oligosaccharides containing glucose. obtained using this trisaccharide as substrate in glucose-al-3-glucose-a-O(CH₂) COOCH,. absence (x-x) and presence of the inhibitor 1- deoxynorjirimycin at concentrations of 50 μM (-), (0-0), and 200 μM (A-A) were used to prepare the Kinetic measurements the Lineweaver-Burk plot below: 1.5 1.0 0.5 0.0 -1.0 0.0 One substrate for 1.0 2.0 100 }M 1/Trisaccharide (mM)-! Estimate the values for Vmax and KM for the trisaccharide substrate in the absence of the inhibitor. Determine whether inhibition by 1-deoxynorjirimycin is competitive, non-competitive or neither.
