Purification and properties of beta-N-acetylglucosaminidase from Escherichia coli.
beta-N-acetylglucosaminidase (EC 3.2.1.30) has been purified from Escherichia coli K-12 to near homogeneity based on polyacrylamide gel electrophoresis in both 0.5% sodium dodecyl sulfate and in 6 M urea at pH 8.5. The purified enzyme shows a pH optimum of 7.7 and the Km for p-nitrophenyl-beta-D-2-acetamido-2-deoxyglucopyranoside is 0.43 mM. The molecular weight of this enzyme, determined by bo...
متن کاملPurification and Properties of an Endo-P-iv-acetylglucosaminidase
An enzyme that hydrolyzes di-N-acetylchitobiose linkages in oligosaccharides and glycoproteins was purified to homogeneity from cultural filtrates of Streptomyces griseus. The molecular weight of the enzyme, determined by sedimentation equilibrium analysis, is 27,200 f ZOO, and it appears to consist of a single polypeptide chain. This apparent endo/3-N-acetylglucosaminidase was completely stabl...
متن کاملIn vivo production of non-glycosylated recombinant proteins in Nicotiana benthamiana plants by co-expression with Endo-β-N-acetylglucosaminidase H (Endo H) of Streptomyces plicatus
A plant transient expression system, with eukaryotic post-translational modification machinery, offers superior efficiency, scalability, safety, and lower cost over other expression systems. However, due to aberrant N-glycosylation, this expression system may not be a suitable expression platform for proteins not carrying N-linked glycans in the native hosts. Therefore, it is crucial to develop...

متن کاملHigh-Level Expression of Endo-β-N-Acetylglucosaminidase H from Streptomyces plicatus in Pichia pastoris and Its Application for the Deglycosylation of Glycoproteins
Endo-β-N-acetylglucosaminidase H (Endo H, EC3.2.1.96) is a glycohydrolase that is widely used in the study of glycoproteins. The present study aimed to assess the effect of high-level endo-β-N-acetylglucosaminidase H expression in Pichia pastoris. The DNA coding sequence of this enzyme was optimized based on the codon usage bias of Pichia pastoris and synthesized through overlapping PCR. This n...
