Chains	Accession	Name	Description	Comments	Source
A	PF05195	Aminopeptidase P, N-terminal domain (AMP_N)	Aminopeptidase P, N-terminal domain	This domain is structurally very similar [1] to the creatinase N-terminal domain (Pfam:PF01321). However, little or no sequence similarity exists between the two families.	Domain
A	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
