Description

• Endoglycoceramidase I (EGCase I) is a glycolipid-specific hydrolase that cleaves the glycosidic linkage between oligosaccharide and ceramide of various glycosphingolipids (GSLs) under conditions requiring a detergent or a cofactor Activator II. The EGCase I gene is derived from Rhodococcus equi and its recombinant protein is expressed in Rhodococcus erythropolis.

Unit Definition

• One unit (U) of EGCase I is defined as the amount required to hydrolyze 1 μmol of ganglioside GM1 per minute at 37°C under the condition of pH 5.5.

Assay Conditions

• Reaction conditions: 50 mM sodium acetate containing 0.4% Triton X-100, pH 5.5
  The reaction mixture includes the enzyme and 100 nmol of GM1 in 50 μL. The mixture is incubated at 37°C for 15 minutes. Quantification of reducing end of released oligosaccharides is measured by the modified Somogyi-Nelson method (see the following reference).

Storage

• Store at -20°C. Avoid repetitive freezing and thawing. After thawing the product, it’s recommended to store at 4°C and use it within a few weeks.
