Taxonomic identifier	1467 [NCBI]
Taxonomic lineage	Bacteria › Firmicutes › Bacillales › Bacillaceae › Bacillus

Protein attributes

Sequence length	269 AA.
Sequence status	Complete.

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 2 calcium ions per subunit.
Subcellular location	Secreted.
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.
