Subtilisin E

Gene

aprE

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Subtilisin is an extracellular alkaline serine protease, it catalyzes the hydrolysis of proteins and peptide amides.

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.

Catalytic activityi

Hydrolysis of proteins with broad specificity for peptide bonds, and a preference for a large uncharged residue in P1. Hydrolyzes peptide amides.
