Chondroitin sulfate ABC exolyase

In enzymology, a chondroitin-sulfate-ABC exolyase (EC 4.2.2.21) is an enzyme that catalyzes the chemical reaction

Exolytic cleavage of disaccharide residues from the non-reducing ends of both polymeric chondroitin sulfates and their oligosaccharide fragments

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is chondroitin-sulfate-ABC exolyase. Other names in common use include chondroitinase (ambiguous), chondroitin ABC eliminase (ambiguous), chondroitinase ABC (ambiguous), chondroitin ABC lyase (ambiguous), chondroitin sulfate ABC lyase (ambiguous), ChS ABC lyase (ambiguous), chondroitin sulfate ABC exoeliminase, chondroitin sulfate ABC exolyase, and ChS ABC lyase II.
