A number of enzyme have been reported to catalyze the hydrolysis of glycosidic linkages in glycoproteins at N-acetylgalactosamine residues, exhibiting specificities at either the a- or the /3-linkage. Enzymes that are reported to act on both a- and /3-linkages have to be clearly characterized as to their specificity. [Pg.227]

See section 4.1.3.4, subheading Calculation. As N-acetylgalactosamine-6-sul-fatase activity is fairly low in leukocytes, results should be expressed as nmol/mg protein-17 h. [Pg.316]

For cells with /1-galactosidase deficiency (GM1 gangliosidosis or Morquio type as well as I-cell disease), the measured enzyme activity will be significantly lower than the true enzyme activity. In addition, cases of multiple sulfatase deficiency will also show low N-acetylgalactosamine-6-sulfatase activity. Therefore, arylsulfatase A or another sulfatase, as well as /1-galactosidase activities should also be determined in case of suspicious results. To exclude poor sample quality, the determination of a-mannosidase is recommended. [Pg.317]
