A new type of hyaluronidase was isolated from squid cranial cartilage. The enzyme seems to be localised extracellularly, since it is extracted from the tissue by 0.5 M sodium acetate, pH 7.0, in the presence of proteinase inhibitors. Degradation studies suggest that the enzyme belongs to the family of endoglycosidases generating oligosaccharides of rather large size. The best activity of the enzyme was observed at pH 7.0 and 37 degrees C and the optimum buffer for digestion was 0.15 M Tris acetate. It is inactive in sodium phosphate, morpholine acetate and HEPES buffers. The enzyme degrades aggrecan, hyaluronan, chondroitin sulphate and oversulphated chondroitin sulphate.

UI MeSH Term Description Entries
D002356 Cartilage A non-vascular form of connective tissue composed of CHONDROCYTES embedded in a matrix that includes CHONDROITIN SULFATE and various types of FIBRILLAR COLLAGEN. There are three major types: HYALINE CARTILAGE; FIBROCARTILAGE; and ELASTIC CARTILAGE. Cartilages
D002809 Chondroitin Sulfates Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.

D006821 Hyaluronoglucosaminidase An enzyme that catalyzes the random hydrolysis of 1,4-linkages between N-acetyl-beta-D-glucosamine and D-glucuronate residues in hyaluronate. (From Enzyme Nomenclature, 1992) There has been use as ANTINEOPLASTIC AGENTS to limit NEOPLASM METASTASIS.
