Protein attributes
| Sequence length | 420 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Subtilisin is an extracellular alkaline serine protease, it catalyzes the hydrolysis of proteins and peptide amides. |
| Catalytic activity | Hydrolysis of proteins with broad specificity for peptide bonds, and a preference for a large uncharged residue in P1. Hydrolyzes peptide amides. |
| Cofactor | Binds 1 calcium ion per subunit Potential. |
| Subcellular location | |
| Miscellaneous | Secretion of subtilisin is associated with onset of sporulation, and many mutations which block sporulation at early stages affect expression levels of subtilisin. However, subtilisin is not necessary for normal sporulation. |
| Sequence similarities | Belongs to the peptidase S8 family. |
| biophysicochemical properties | Temperature dependence: Still active at temperatures close to 0 degrees Celsius. Thermolabile. |
