A, B	PF04151	Bacterial pre-peptidase C-terminal domain (PPC)	Bacterial pre-peptidase C-terminal domain	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. ...	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
