Hondroitin-sulfat-ABC endolijaza (EC 4.2.2.20, hondroitinaza, hondroitin ABC eliminaza, hondroitinaza ABC, hondroitin ABC lijaza, hondroitin sulfat ABC lijaza, ChS ABC lijaza, hondroitin sulfat ABC endoeliminaza, hondroitin sulfat ABC endolijaza, ChS ABC lijaza I) je enzim sa sistematskim imenom hondroitin-sulfat-ABC endolijaza.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- Endolitičko razlaganje (1->4)-beta-galaktozaminskih veza između N-acetilgalaktozamina i bilo D-glukuronske kiseline ili L-iduronske kiseline čime se formira smeša Delta4-nezasićenih oligosaharida različitih veličina koji se ultimatno degradiraju do Delta4-nezasićenih tetra- i disaharida
Ovaj enzim degradira mnoštvo glikozaminoglikana hondroitin-sulfat- i dermatan-sulfatnog tipa.
