Chondroitin ABC lyase (EC 4.2.2.20 EC 4.2.2.21 , chondroitinase , chondroitin ABC eliminase , chondroitinase ABC ) is an enzyme with systematic name chondroitin ABC lyase .[ 1] [ 2] catalyses the following chemical reaction
Eliminative degradation of polysaccharides containing 1,4-beta-D-hexosaminyl and 1,3-beta-D-glucuronosyl or 1,3-alpha-L-iduronosyl linkages to disaccharides containing 4-deoxy-beta-D-gluc-4-enuronosyl groups This enzyme acts on chondroitin 4-sulfate, chondroitin 6-sulfate and dermatan sulfate.
Following a spinal cord injury , this enzyme can be used to erode scar tissue that can interfere with regeneration.[ 3]
