Purified bovine testicular hyaluronidase (hyaluronate 4-glycanohydrolase, EC 3.2.1.35) was inactivated by butane-2,3-dione in either borate or Hepes buffer, pH 8.3. The presence of borate enhanced the inactivation process which followed pseudo-first-order kinetics with a calculated second-order rate constant of 13.54M-1
