ENZYME entry: EC 3.4.22.69
| Accepted Name |
|---|
| SARS coronavirus main proteinase.
|
| Alternative Name(s) |
|---|
| 3C-like protease. |
| 3cLpro. |
| Coronavirus 3C-like protease. |
| SARS coronavirus main protease. |
| SARS-CoV 3CLpro enzyme. |
| Severe acute respiratory syndrome coronavirus main protease. |
| Reaction catalysed |
|---|
| TSAVLQ-|-SGFRK-NH(2) and SGVTFQ-|-GKFKK the two peptides corresponding to the two self-cleavage sites of the SARS 3C-like proteinase are the two most reactive peptide substrates. The enzyme exhibits a strong preference for substrates containing Gln at P1 position and Leu at P2 position |
| Comment(s) |
|---|
- SARS coronavirus main protease is the key enzyme in SARS coronavirus
replicase polyprotein processing.
- Belongs to peptidase family C30.
