This domain is normally found at the C-terminus of secreted bacterial peptidases. They are not present in the active peptidase. It is possible that they fulfill a similar role to the PKD (Pfam:PF00801) domain, which also are found in this context. Visual analysis suggests that PKD and PPC are distantly related (personal obs:Bateman A, Yeats C).	Domain

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).
