Function
[UCDH_STRA3] Catalyzes the hydrolysis of unsaturated hyaluronate and chondroitin disaccharides. Also degrades unsaturated heparin disaccharides. Releases 4-deoxy-4,5-didehydro D-glucuronic acid or 4-deoxy-4,5-didehydro L-iduronic acid from chondroitin disaccharides, hyaluronan disaccharides and heparin disaccharides and cleaves both glycosidic (1->3) and (1->4) bonds. Prefers sulfated glycosaminoglycans compared to unsulfated glycosaminoglycans. Probably required for mammalian cells invasion through the degradation of extracellular sulfated glycosaminoglycans such as chondroitin and hyaluronan.[1] [2]
