Description
Application
PNGase F from Elizabethkingia meningoseptica has been used in deglycosylation
of recombinant soybean agglutinin (rSBA) in Nicotiana benthamiana (NbrSBA) and Solanum tuberosum (StrSBA)
of frontal cortical lysate to verify the glycosylation profile of β-secretase (BACE proteins)
of cell lysate for evaluating the siRNA silencing of cellular prion protein (PrPc) post transfection
PNGase F is a glycosylasparaginase used to deglycosylate proteins. It is widely used in structure-function studies of glycoproteins.
Used to deglycosylate protein.
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.
PNGase F cleaves an entire glycan from a glycoprotein provided the glycosylated asparagine moiety is substituted on its amino and carboxyl terminus with a polypeptide chain. It deaminates the asparagine to aspartic acid, but leaves the oligosaccharide intact. PNGase F will not remove oligosaccharides containing α(1-3)-linked core fucose, commonly found in plant glycoproteins. A tripeptide with the oligosaccharide-linked asparagine as the central residue is the minimal substrate for PNGase F.
Packaging
Each set includes enzyme, two formulations of 5× reaction buffer (for routine and mass spectrometry downstream analysis), detergent and denaturation solutions
Other Notes
One unit will catalyze the release of N-linked oligosaccharides from 1 micromole 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.
