Inulin catabolism in Saccharomyces cerevisiae is affected by some key glycosylation sequons of invertase Suc2.

Carbohydrate chains at N4, N45, N78 and N146 played an important role in modulating Suc2 activity and inulin catabolism of the S. cerevisiae strain. These key N-deglycosylation sequons should become potential targets for rational engineering of S. cerevisiae strains to enhance the ethanol production from inulin.
