ENZYME entry: EC 4.2.2.1
| Accepted Name |
|---|
| Hyaluronate lyase.
|
| Alternative Name(s) |
|---|
| Hyaluronidase. |
| Mucinase. |
| Spreading factor. |
| Reaction catalysed |
|---|
| 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 |
| Comment(s) |
|---|
- 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.
