Peptide N-glycosidase from Flavobacterium meningosepticum cleaves complex as well as neutral glycoproteins (Plummer, T.H., Jr., Elder, J.H., Alexander, S., Phelan, A.W., and Tarentino, A.L. (1984) J. Biol. Chem. 259, 10700-10704). Examples of neutral glycoprotein substrates include ribonuclease B (one high mannose oligosaccharide chain) and yeast external invertase (nine chains/invertase subunit). The rate of deglycosylation by the glycosidase was greatly enhanced if the glycoprotein substrate was denatured prior to enzyme treatment, from a low of 11-fold for external invertase to a high of 844-fold for ribonuclease B. Peptide N-glycosidase F was unable to cleave the asparaginyl-N-acetylglucosamine bond in endo-beta-N-acetylglucosaminidase H-modified external invertase or ribonuclease B, although that in similarly modified glycopeptide substrate was cleaved. Ribonuclease B was digested sequentially with various exoglycosidases to produce an oligosaccharide chain of varied length. Using the resulting forms of ribonuclease B as substrates for peptide N-glycosidase F, the minimum oligosaccharide chain for cleavage was the di-N-acetyl-chitobiosyl core unit.
