Application

Used to deglycosylate protein.

PNGase F from Elizabethkingia miricola has been used for the deglycosylation of the proteins.

Biochem/physiol Actions

Cleaves an entire glycan from a glycoprotein provided the glycosylated asparagine moiety is substituted on its amino and carboxyl terminus with a polypeptide chain.

General description

PNGase F (Peptide N-glycosidase F) cleaves asparagine-linked glycoproteins, which produces carbohydrate-free peptides and detached full-length oligosaccharides.

Physical form

Supplied as a solution in 20 mM Tris HCl, pH 7.5, 50 mM NaCl and 1 mM EDTA

Unit Definition

One unit will catalyze the release of N-linked oligosaccharides from 1 nanomole of denatured ribonuclease B in one minute at 37°C at pH 7.5 monitored by SDS-PAGE. One Sigma unit of PNGase F activity is equal to 1 IUB milliunit.
