pubmed:abstractText |
Beta-N-Acetylhexosaminidase was purified from the rabbit seminal plasma by a three-step procedure involving hydroxyapatite, Sephadex G-200 and concanavalin A--Sepharose chromatography. The specific activity of the purified preparation was 56mu mol/min per mg of protein, which represented a 226-fold purification and a 54% yield of the enzyme activity. The purified enzyme was electrophoretically homogeneous. The homogeneous enzyme showed optimal activity at pH4.0. The apparent Km value and Vmax. were 1.4 mM and 56mu mol/min per mg of protein respectively. Metal ions such as Ag + and Hg2+ and p-chloromercuribenzoate strongly inhibited the enzyme activity. The treatment of rabbit ova with a mixture of Beta-N-acetylhexosaminidase and arylsulphatase A results in the swelling of the zona pellucida.
