These enzymes were shown to be free of protease activity. Under correct conditions, the endoglycosidases could release one or both carbohydrate chains. Rhodopsin and opsin at concentrations between 2 and 65 nmol ml-1 were cleaved, with more complete deglycosylation occurring at the higher ...
Inverting enzymes operate by a single nucleophilic substitution, while retaining GHs follow a double displacement mechanism via formation and subsequent hydrolysis of a covalent glycosyl-enzyme intermediate (glycosylation and deglycosylation steps as shown in Figure 1). Both types of reactions involve ...
It is proposed that the catalysis of GH1 enzymes follows a double-displacement mechanism involving a glycosylation and a deglycosylation steps. In this article, the deglycosylation step was studied using quantum mechanical/molecular mechanical (QM/MM) approach. The calculation results reveal that the nu...
Bacterial pathogens have evolved intricate mechanisms to evade the human immune system, including the production of immunomodulatory enzymes. Streptococcus pyogenes serotypes secrete two multi-modular endo-β-N-acetylglucosaminidases, EndoS and EndoS2, that specifically deglycosylate the conserved N-glycan...

N-Glycosidase-carbohydrate-binding module fusion proteins as immobilized enzymes for protein deglycosylation. A carbohydrate-binding module (CBM) was fused to the N-termini of mannosyl-glycoprotein endo-beta-N-acetylglucosaminidase (EndoF1) and peptide N-glycosidas... EM Kwan,AB Boraston,BW Mclean,...

The initial rate of clearance of infused enzyme was increased greater than 10-fold for the asialo-, agalacto- and ahexoenzymes over that of native glucocerebrosidase. Incorporation of asialo enzyme was increased in hepatocytes over that of native enzyme, while the distribution of agalacto- and ...
One of these enzymes,peptide- N- ( N- acetyl- 尾 -glucosaminyl)asparagine amidase (PNGase), is actually an amidase (amidohydrolase) that hydrolyzes the glycosylamine linkage of a wide variety of glycoprotein/glycopeptide substrates, generating an aspartic acid residue at the site of hydrolysis, ...
UDP-glucuronosyltranferases (UGT) enzymes are also abundantly expressed in small intestines, which are the sites of first isoflavonoids metabolism after oral administration. Therefore, it is necessary to study the corresponding metabolic characteristics of calycosin and CG in intestinal microsomes. In ...
