Characterization of Hyaluronidase 4 Involved in the Catabolism of Chondroitin Sulfate [PDF]
Molecules, 2022 Hyaluronidases (HYALs) are endo-beta-N-acetylhexosaminidases that depolymerize not only hyaluronan but also chondroitin sulfate (CS) at the initial step of their catabolism. Although HYAL1 hydrolyzes both CS and HA, HYAL4 is a CS-specific endoglycosidase.

Journal of Biological Chemistry, 1983 The two neutral beta-N-acetylhexosaminidases of rat brain have been purified by procedures involving extraction, concanavalin A-Sepharose, ammonium sulfate precipitation, DEAE-cellulose, hydroxyapatite, Sepharose 4B, and an affinity chromatography with 2-acetamido-N-(epsilon-aminocaproyl)-2-deoxy-beta-galactopyranosylamine bound to Sepharose.

Purification and characterization of an extracellular beta-n-acetylhexosaminidase from Paecilomyces persicinus [PDF]
Journal of Bacteriology, 1979 Both beta-N-acetylglucosaminidase nad beta-N-acetylgalactosaminidase activities were detected in the culture fluids of Paecilomyces persicinus P-10 after growth in a soybean meal-corn meal medium. The active material was purified by means of protamine sulfate fractionation and ultrafiltration, followed by ion exchange and gel chromatography.

Purification and Characterization of .BETA.-N-Acetylhexosaminidase from Trichoderma harzianum.
Agricultural and Biological Chemistry, 1991 beta-N-Acetylhexosaminidase was produced by Trichoderma harzianum cultivated with chitin as the growth substrate. The enzyme was purified 13.2-fold to homogeneity by ultrafiltration and sequential chromatography on SP-Toyopearl and Sephacryl S-200. The molecular weight of the enzyme was estimated to be about 150,000 by gel filtration.

Purification and characterization of .BETA.-N-acetylhexosaminidase from Penicillium oxalicum.
Agricultural and Biological Chemistry, 1985 β-N-Acetylhexosaminidase (EC 3.2.1.52) was purified from the culture filtrate of Penicillium oxalicum by fractionation with ammonium sulfate followed by successive column chromatographies with DEAE-cellulose, hydroxylapatite, Sephadex G-150 and Con A-Sepharose 4B. The purified enzyme was found to be homogeneous on polyacrylamide gel electrophoresis and

Purification and characterization of .BETA.-N-acetylhexosaminidase from Pycnoporus cinnabarinus.
Agricultural and Biological Chemistry, 1981 β-N-Acetylhexosaminidase (EC 3.2.1.52) was purified from the culture filtrate of Pycnoporus cinnabarinus to homogeneity by polyacrylamide disc gel electrophoresis. The ratio of β-GlcNAcase activity to β-GalNAcase activity remained constant during the purification process.

Chemical and Pharmaceutical Bulletin, 1985 The lysozyme assay using 4-methylumbelliferyl tetra-N-acetyl-β-chitotetraoside as a substrate was found to show increased sensitivity for lysozyme in the presence of jack bean β-N-acetylhexosaminidase (NAHase). The assay system containing NAHase gave a linear dose-response curve in the range of 10-70μg of lysozyme under conditions of 20-60 min ...

Age-related profile of beta-N-acetylhexosaminidase glycosylation in rat liver.
Acta Biochimica Polonica, 1998 Beta-N-acetylhexosaminidase was prepared from a liver lysosomal fraction obtained from rats between 18 days of gestation (group I) and 72 weeks of age (groups II-VI). A glycan chain analysis was performed after an electrophoresis and blotting, followed by a very sensitive detection system with highly specific digoxigenin-labelled lectins.

Liberation of N-acetylglucosamine-6-sulfate by human beta-N-acetylhexosaminidase A.
Journal of Biological Chemistry, 1981 The first step of the degradation of p-nitrophenyl-6-sulfo-2-acetamido-2-deoxy-beta-D-glucopyranoside and of keratan sulfate-derived oligosaccharides bearing N-acetylglucosamine-6-sulfate residues at the nonreducing end was considered to be accomplished by the action of a specific sulfatase (Kresse, H., Paschke, E., von Figura, K., Gilberg, W., and ...
