Enzyme Information
| 4.2.2.1 |
Hyaluronate lyase.
based on mapping to UniProt Q54873
Cleaves hyaluronate chains at a beta-D-GlcNAc-(1->4)-beta-D-GlcA bond, ultimately breaking the polysaccharide down to 3-(4-deoxy-beta-D-gluc-4- enuronosyl)-N-acetyl-D-glucosamine.
-!- The enzyme catalyzes the degradation of hyaluronan by a beta- elimination reaction. -!- Also acts on chondroitin. -!- The product is more systematically known as 3-(4-deoxy-alpha-L-threo- hex-4-enopyranosyluronic acid)-2-acetamido-2-deoxy-D-glucose. -!- Formerly EC 4.2.99.1.
