General description
Note: 1 mU = 1 milliunit.
Recombinant, Elizabethkingia meningosepticum endoglycosidase F2 expressed in E. coli. Cleaves asparagine-linked or free oligomannose and biantennary complex oligosaccharides from glycoproteins. It cleaves between the two N-acetylglucosamine residues in the diacetylchitobiose core of the oligosaccharide generating a truncated sugar molecule with one N-acetylglucosamine residue remaining on the asparagine. Less sensitive to protein conformation than N-Glycosidase F (Cat. No. 362185) and therefore is more suitable for deglycosylation of native proteins. This enzyme is not active above pH 6.0.
