Answer

Other extracellular products include NADase (leukotoxic), hyaluronidase (which digests host connective tissue, hyaluronic acid, and the organism's own capsule), streptokinases (proteolytic), and streptodornase A-D (deoxyribonuclease activity). [13]

Proteinase, amylase, and esterase are additional streptococcal virulence factors, although the role of these proteins in pathogenesis is not fully understood.
