MeSH Heading: Chondroitin Lyases
Tree Number(s): D08.811.520.241.700.350.500
Unique ID: D002808
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D002808
Annotation: do not confuse with CHONDROITIN ABC LYASE
Scope Note: Enzymes which catalyze the elimination of delta-4,5-D-glucuronate residues from polysaccharides containing 1,4-beta-hexosaminyl and 1,3-beta-D-glucuronosyl or 1,3-alpha-L-iduronosyl linkages thereby bringing about depolymerization. EC 4.2.2.4 acts on chondroitin sulfate A and C as well as on dermatan sulfate and slowly on hyaluronate. EC 4.2.2.5 acts on chondroitin sulfate A and C.
Entry Term(s): Chondroitin AC Lyase; Chondroitin B Lyase; Chondroitin Eliminase; Chondroitin Sulfate Lyase; Chondroitinase-AC II
Registry Number: EC 4.2.2.-
