The multiple forms and kinetic differences of rat colonic beta-N-acetylhexosaminidases.
Biochimica et biophysica acta, 1978Rat colonic beta-N-acetylhexosaminidase (2-acetamido-2-deoxy-beta-D-glucoside acetamidodeoxyglucohydrolase, EC 3.2.1.30) has been separated into three forms by DEAE-cellulose chromatography with an increasing salt gradient. It was not possible to separate the glucosaminidase activity from the galactosaminidase activity by a variety of chromatographic ...

Biochemistry, 1994
Hydrolysis by three beta-N-acetylhexosaminidases (human placenta, jack bean, and bovine kidney) is shown to occur with the retention of anomeric configuration, most likely via a double-displacement mechanism involving the formation and hydrolysis of a glycosyl-enzyme intermediate.

Three beta-N-acetylhexosaminidases [EC 3.2.1.52] and one beta-galactosidase [EC 3.2.1.23] were purified from the culture filtrate of streptococcus 6646 group K by a combination of column chromatographies on p-aminophenyl beta-D-thiogalactopyranoside-substituted Sepharose and N-(paminophenyl)oxamic acid-substituted Sepharose.

Inflammatory Bowel Disease and Serum Beta-N-Acetylhexosaminidase
Enzyme, 1990Serum beta-N-acetylhexosaminidase levels in 49 patients with inflammatory bowel disease (IBD; 23 patients with ulcerative colitis, 10 with Crohn's disease, and 16 with ileostomy after total proctocolectomy) as well as in healthy normal controls were determined.

Elevated β-N-acetylhexosaminidase activity in focal dystonia fibroblasts
Clinica Chimica Acta, 1999Specific activities of beta-D-hexosaminidase, alpha-D-mannosidase, beta-D-galactosidase and beta-D-glucuronidase were determined in fibroblasts of patients with writer's cramp and torticollis. These diseases show degenerative neurological disorders similar to those observed in lysosomal diseases.

β-N-Acetylhexosaminidase Active on Dermatan Sulfate
Enzyme, 1975The dodecasaccharide obtained by treating dermatan sulfate with testicular hyaluronidase, chondroitinase AC, and beta-glucuronidase was incubated with diluted, normal human serum at pH 4.5 or 7.0 followed by chondro-4-sulfatase at pH 7.0. Analyses of the reaction products indicate release of hexosamine but not further degradation of the substrate.

[Localization of beta-n-acetylhexosaminidase in stallion epididymis (author's transl)].
Acta histochemica, 1982The localization of beta-N-acetylhexosaminidase activity in 6 different segments of the epididymis was investigated in 8 stallions using biochemical and histochemical methods. The highest enzyme activity was found in segment D while the other segments displayed a much weaker reaction There was no or only low enzyme activity present in the epididymal ...

Purification and characterization of beta-N-acetylhexosaminidase I from human placenta.
Journal of biochemistry, 1989beta-N-Acetylhexosaminidase (hexosaminidase) I, which has an intermediate charge character between those of hexosaminidases A(alpha beta 2) and B[beta beta)2), was purified 1,500-fold from human placenta by procedures including chromatographies on concanavalin A (Con A)-Sepharose and an immunoadsorbent column.
