General description【一般描述】 | Glycopeptidase found in almonds can be divided into three groups- A, B and C. the optimum pH value and the isoelectric point of glycopeptidase A is 6.0 and 7.7 respectively. It has a preference for glycopeptides with long chains. It is also capable of hydrolyzing intact glycoproteins such as, desialyted human transferrin, ovalbumin etc. These proteins cleave glycoproteins with asialocarbohydrate moieties at their β-aspartyl-glucosylamine linkages. |
Application【应用】 | Glycopeptidase A from almonds is used for deglycosylation. It catalyzes the removal of N-linked oligosaccharide chains and converts Asn residue to Asp. |
Biochem/physiol Actions【生化/生理作用】 | Hydrolyzes an N4-(acetyl-β- |
Unit Definition【单位定义】 | One unit will hydrolyze 1.0 μmole of ovalbumin glycopeptide per min at pH 5.0 at 37℃. |
Physical form【外形】 | Solution in 50% glycerol containing 50 mM citrate-phosphate buffer, pH 5.0, and BSA. |
