The subtilisin propeptides are known to function as molecular chaperones, assisting in the folding of the mature peptidase [1], but have also been shown to act as 'temporary inhibitors' [2].

They appear to have independently and convergently evolved an Asp/Ser/His catalytic triad, like that found in the trypsin serine proteases (see Pfam:PF00089). Structure is an alpha/beta fold containing a 7-stranded parallel beta sheet, order 2314567.
