Protein Glycosylation- ImplicationThere is a large influence of N glycosylation on the thermostability of the hybrid enzyme. 16- and 133-fold decrease of thermostability has been observed after treatment with endoglycosidase H and peptide:N-glycosidase F (that remove glycans). This indicates that N-glycans are a major determinant for the resistance of this hybrid glucanase to thermal inactivation.

Additional CommentsEngineered glycoprotein
The glucanases from which the hybrid enzyme is made, are not glycosylated in their native hosts. Hybrid enzyme containing 16 N-terminal amino acids from Bacillus amyloliquefaciens (1,3-1,4)-beta-glucanase (AMY), and remaining C-terminal part and signal peptide from B. macerans (1,3-1,4)-beta-glucanase (MAC), was expressed in Saccharomyces cerevisiae to see the effect of N-glycosylation on the thermostability of the hybrid enzyme.
