General description

Endoglycosidase H or endo-β-N-acetylglucosaminidase H is an glycohydrolase. It is produced by Streptomyces plicatus and other Streptomyces species.[1]

Biochem/physiol Actions

Endoglycosidase H is involved in cleaving the N-linked glycans present between the two N-acetylglucosamine (GlcNAc) residues in the core of the glycan chain in high-mannose sugars.[2]

Unit Definition

One unit will release N-linked oligosaccharides from 1 μmole of denatured ribonuclease B per min at 37 °C at pH 5.5.

Physical form

Solution in 20 mM Tris HCl, pH 7.5, containing 50 mM NaCl, 1 mM EDTA

Storage Class

12 - Non Combustible Liquids

Questions

  1. Could you provide guidance on adjusting the pH of a solution that has a pH of 7.5, even though the workable pH range mentioned in the data sheet is 5.0–6.0? Specifically, which acid would be best to use for adjusting the pH before using the solution?

    1 answer
    1. Please consider that the condition of the stock enzyme is different from the reaction in which it is used. You will be using a small amount of enzyme in a buffered reaction that is adjusted to the optimal pH by the reaction buffer itself.
