Description
In enzymology, a peptide-N4-(N-acetyl-beta-glucosaminyl) asparagine amidase (EC 3.5.1.52) is an enzyme that catalyzes a chemical reaction that cleaves a N4-(acetyl-beta-D-glucosaminyl)asparagine residue in which the glucosamine residue may be further glycosylated, to yield a (substituted) N-acetyl-beta-D-glucosaminylamine and a peptide containing an aspartate residue. This enzyme belongs to the family of hydrolases, specifically those acting on carbon-nitrogen bonds other than peptide bonds in linear amides.
Abbr
PNGase F, Recombinant (Elizabethkingia meningoseptica)
Species
Elizabethkingia meningoseptica
Applications
Highly purified material can be used for preparative deglycosylation or for analytical applications in gel, in solution, or on blot membranes. The enzyme can be removed from preparative operations by utilizing its C-teminal 6x histidine fusion tag. Used to deglycosylate protein.
Package
PNGase F was used for deglycosylation of P-glycoprotein in a study to investigate the dual impact of statins on p-glycoprotein and its effect on doxorubicin cytotoxicity in human neuroblastoma cells. It was used to treat a purified protein, mouse cone ultraviolet (MUV) pigment, before use in quantitative immunoblot analysis in a study It is used to deglycosylate N-linked glycoproteins. Highly purified material can be used for preparative deglycosylation or for analytical applications in gel, in solution, or on blot membranes. The enzyme can be removed from preparative operations by utilizing its C-teminal 6x histidine fusion tag.
