title: Heparin-sepharose affinity chromatography for purification of bull seminal-plasma hyaluronidase.
abstract: Bull seminal-plasma hyaluronidase was purified 180-fold by chromatography on concanvalin A-Sepharose, heparin Sepharose, Sephadex G-200 and Sephacryl S-200. With hyaluronic acid as the substrate, the specific activity and turnover number of purified hyaluronidase were 3.63 mumol/min per mg (104000 National Formulary units/mg of protein) and 214 min-1 (mol of product formed/mol of enzyme per min) respectively. Polyacrylamide-gel electrophoresis indicated that the purified enzyme migrated as a single band on 7.5 and 10% (w/v) gels at pH 4.3 and 5.3. Bull seminal-plasma hyaluronidase was markedly inhibited by hydroxylamine, phenylhydrazine and semicarbazide. Purified hyaluronidase (1.25 munits; 1 unit = 1 mumol of N-acetylglucosamine liberated/min at 37 degrees C) dispersed the cumulus clot of rabbit ova in 1 h at 22 degrees C.
