Chains	Accession	Name	Description	Comments	Source
A, B	PF00557	Metallopeptidase family M24 (Peptidase_M24)	Metallopeptidase family M24	This family contains metallopeptidases. It also contains non-peptidase homologues such as the N terminal domain of Spt16 which is a histone H3-H4 binding module [3].	Domain
A, B	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
