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] This enzyme 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.
Uses
Following a spinal cord injury, this enzyme can be used to erode scar tissue that can interfere with regeneration.[3]
