Description

Application

Recombinant PNGase F has been purified by affinity chromatography and dialyzed into a 50% glycerol solution with 10 mM potassium phoosphate pH 7.5 to produce a stable product. The product contains low levels of buffer salts. This 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-terminal 6x histidine fusion tag. PNGase F from Elizabethkingia meningoseptica has been used in deglycosylation assay in human plasma samples and in deglycosylation of chondroitin sulfate proteoglycan.

Actions biochimiques/physiologiques

PNGase F from Elizabethkingia meningoseptica has glycan-binding catalytic domain and a bowl-like domain at the N-terminus. It 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 is cost-effectively produced on a large scale in prokaryotic hosts and requires divalent zinc ions for its enzymatic activity.
