structural analyses performed with the three glycosidases endo-beta-n-acetylglucosaminidase h ( endoglycosidase h ) , endo-beta-n-acetylglucosaminidase f ( endoglycosidase f ) , and endo-alpha-n-acetylgalactosaminidase demonstrated that gp118 was predominantly an n-linked complex type glycoprotein built upon a polypeptide backbone of approximately 79,000 da .
