Abstract

A recently described mammalian wound hyaluronidase is successfully characterized and partially purified in the current study. Peak enzyme activity occurred on postwound day 7, pH optimum 4.5. Both crude and purified would enzyme exhibited endoglycosidic activity against hyaluronate and chondroitin-4-sulfate but not against chondroitin-6-sulfate or dermatan sulfate. A 5.3 fold increase in activity was obtained by the DEAE-Sephadex purification technique described. Polyacrylamide gel electrophoresis yielded a single major band near the gel's midrange and one minor band of less electrophoretic mobility. These enzyme characteristics support a biochemical analogy between tissue repair in skin and numerous developmental systems and may provide a simple means for enzymatic differentiation among chondroitin sulfate isomers.
