Pneumococcal hyaluronidase: a product of enzyme in normal human flora
Hyaluronidase degrades hyaluronan or hyaluronic acid (HA), a major component of extracellular matrix in human connective tissues. Among three types of hyaluronidase family members, hyaluroglucosaminidase which is extracted from vertebrate testes has been widely used in various medical or cosmeticall...
