CC   -!- FUNCTION: Hydrolyzes high molecular weight hyaluronic acid to produce
CC       small oligosaccharides (By similarity). Is an important component of
CC       the venom, since anti-hyaluronidase serum effectively neutralizes the
CC       lethal effet of the venom injected into mice. It may act by increasing
CC       the diffusion of other venom proteins by degrading the extracellular
CC       matrix. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Random hydrolysis of (1->4)-linkages between N-acetyl-beta-D-
CC         glucosamine and D-glucuronate residues in hyaluronate.; EC=3.2.1.35;
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|Ref.2}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland. {ECO:0000269|Ref.2}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 56 family. {ECO:0000255}.
