pH-sensitive dissociation and association of beta-N-acetylhexosaminidase from boar sperm acrosome.

Biology of reproduction, 1994
beta-N-Acetylhexosaminidase (beta-Hex, EC, 3.2.1.52) was released from cauda epididymal boar sperm by treatment with ionophore A23187, indicating that this enzyme is localized in the acrosome. beta-Hex was extracted on a large scale, with 2% acetic acid containing 0.2% Brij 35, from washed ejaculated sperm.

Assay of beta-N-acetylhexosaminidase isoenzymes in different biological specimens by means of determination of their activation energies.

Clinical chemistry, 1998
The activation energy (Ea) of beta-N-acetylhexosaminidase (Hex, EC 3.2.1.52) was determined with 3,3'-dichlorophenylsulfonphthaleinyl-N-acetyl-beta-D-glucosaminide as substrate, with a much higher value being found for the Hex B isoenzyme (Ea = 75.1 kJ/mol) than for the Hex A isoenzyme (Ea = 41.8 kJ/mol). This fact allowed for the development of a fast

beta-N-acetylhexosaminidases from Serratia marcescens.

Microbios, 1992
Two forms of beta-N-acetylhexosaminidase from Serratia marcescens with an optimum pH of 5.0 and 6.5, respectively, to 4-methylumbelliferyl-2-acetamido-2-deoxy-beta-D-glucopyranoside were separated by DEAE-cellulose chromatography and Sephacryl S-200 chromatography.
