Structural insights of two novel N-acetyl-glucosaminidase enzymes through in silico methods.

ABSTRACT: EndoBI-1 and EndoBI-2 are two endo- β-N- acetylglucosaminidase isoenzymes that cleave N-N'- diacetylchitobiosyl moieties found in various types of native N -glycans. These N -glycans are indigestible by human infants and adults due to the lack of responsible glycosyl hydrolases and they act as selective prebiotics for a probiotic microorganism, Bifidobacterium longum subsp . infantis , in the large intestine. The selectivity and the thermostability of EndoBI-1 and EndoBI-2 suggest that these enzymes may be useful for many scientific and industrial applications. In this study, the growing numbers of homologous sequences in different databases were exploited in a comparative approach to investigate structural properties of EndoBI-1 and EndoBI-2 enzym
