In enzymology a chondroitin-sulfate-ABC endolyase (EC 4.2.2.20) is an enzyme that catalyzes the chemical reactionEndolytic cleavage of beta-14-galactosaminic bonds between N-acetylgalactosamine and either D-glucuronic acid or L-iduronic acid to produce a mixture of Delta4-unsaturated oligosaccharides of different sizes that are ultimately degraded to Delta4-unsaturated tetra- and disaccharidesThis enzyme belongs to the family of lyases specifically those carbon-oxygen lyases acting on polysaccharides.
