Általános leírás

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.

Alkalmazás

Glycopeptidase A from almonds is used for deglycosylation. It catalyzes the removal of N-linked oligosaccharide chains and converts Asn residue to Asp.

Biokémiai/fiziológiai hatások

Hydrolyzes an N4-(acetyl-β-D-glycosaminyl)asparagine in which the N-acetyl-D-glucosamine residue may be further glycosylated, yielding a (substituted) N-acetyl-β-D-glucoaminylamine and the peptide containing an aspartic residue.

Egység definíció

One unit will hydrolyze 1.0 μmole of ovalbumin glycopeptide per min at pH 5.0 at 37°C.

Fizikai forma

Solution in 50% glycerol containing 50 mM citrate-phosphate buffer, pH 5.0, and BSA.

The glycopeptidase preparation that has been isolated from almond emulsin and acts on beta-aspartylglycosylamine linkages in glycopeptides was separated into three active fractions by DEAE-cellulose column chromatography. The three discrete species of glycopeptidase (Groups A, B and C) have been

The beta-subunit of dog kidney (Na+ + K+)-ATPase is a sialoglycoprotein and contains three potential N-glycosylation sites. In this study, the oligosaccharide chains of purified dog kidney beta-subunit were labeled with tritium by oxidation with sodium periodate or galactose oxidase

Proteome data of potato (Solanum tuberosum) tuber juice and of purified potato tuber vacuoles indicated that mature patatins may perhaps lack a C-terminal propeptide. We have confirmed this by complete mass spectrometric sequencing of a number of patatin variants as
