生化/生理作用
Chondroitinase AC is an eliminase that degrades chondroitin sulfates A and C, but not chondroitin sulfate B. The enzyme cleaves, via an elimination mechanism, sulfated and non-sulfated polysaccharide chains containing (1-4) linkages between hexosamines and glucuronic acid residues. The reaction yields oligosaccharide products, mainly disaccharides, containing unsaturated uronic acids that can be detected by UV spectroscopy at 232 nm.
The enzyme shows approximately equal activity with chondroitin sulfates A and C, while the activity observed with chondroitin sulfate B is approximately 7% of this value. This activity is most likely due to the presence of chondroitin sulfates A and C (10%) in the chondroitin sulfate B.

Chondroitin and dermatan sulfate (CS and DS) chains were isolated from bovine tracheal cartilage and pig intestinal mucosal preparations and fragmented by enzymatic methods. The oligosaccharides studied include a disaccharide and hexasaccharides from chondroitin ABC lyase digestion as well as

Glycosaminoglycans (GAGs) are a family of complex polysaccharides involved in a diversity of biological processes, ranging from cell signaling to blood coagulation. Chondroitin sulfate (CS) and dermatan sulfate (DS) comprise a biologically important subset of GAGs. Two of the important
