PF04151Bacterial pre-peptidase C-terminal domain (PPC)Bacterial pre-peptidase C-terminal domainThis domain is normally found at the C-terminus of secreted bacterial peptidases. They are not present in the active peptidase.

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).

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.

The beta sheet of this domain packs tightly to the two nearly parallel alpha helices 2 and 3 located at the surface of the subtilisin domain. Gln105 and Asp107 of the N-propeptide domain also bind to the N-termini of these two alpha-helices to form helix caps [1].
