A	PF16188	C-terminal region of peptidase_M24 (Peptidase_M24_C)	C-terminal region of peptidase_M24	This is a short region at the C-terminus of a number of metallo-peptidases of the M24 family.	Domain
A	PF01321	Creatinase/Prolidase N-terminal domain (Creatinase_N)	Creatinase/Prolidase N-terminal domain	This family includes the N-terminal non-catalytic domains from creatinase and prolidase. The exact function of this domain is uncertain.	Domain
